The following detailed description of implementations of the present application is provided in conjunction with specific embodiments.

As shown in fig. 1-3, the embodiment of the present application provides an electric kettle, which includes a kettle body 1, an inner container 2 disposed in the kettle body 1, and a heating element 3 disposed in the kettle body 1 and in heat-conducting contact with the inner container 2; the inner container 2 is used for containing fluid such as water, and the heating component 3 is used for heating the inner container 2, so as to heat the fluid in the inner container 2.

The heating assembly 3 comprises a heat transfer plate 301 in heat conduction contact with the inner container 2, a heating tube 302 in heat conduction contact with one side of the heat transfer plate 301 far away from the inner container 2, and a heat resistance sheet 303 arranged on the heat transfer plate 301; the heat pipe 302 is a heating element, and heat generated by energization is transferred to the heat transfer plate 301, and the heat transfer plate 301 transfers the heat to the inner container 2.

The heat blocking sheet 303 has a thermal conductivity smaller than that of the heat transfer plate 301, and thus the heat transfer efficiency of the heat blocking sheet 303 is lower than that of the heat transfer plate 301. The surface of the heat transfer plate 301 facing the inner container 2 is provided with a mounting groove 3011, and the heat blocking sheet 303 is disposed in the mounting groove 3011, so that the heat transfer plate 301 is provided with the mounting groove 3011 and the heat blocking sheet 303 is mounted in a lower heat transfer efficiency relative to other areas of the heat transfer plate 301.

The surface of the heat transfer plate 301 in heat conduction contact with the heating tube 302 is a thermal contact surface 3013, that is, the heat of the heating tube 302 is transferred to the heat transfer plate 301 through the thermal contact surface 3013, the temperature at the thermal contact surface 3013 of the heat transfer plate 301 is the highest and is obviously higher than that at other positions, if the heat transfer plate 301 is directly in heat conduction contact with the inner container 2, the temperature at the position of the inner container 2 corresponding to the thermal contact surface 3013 is the highest, so that the heating is not uniform, a lot of bubbles are generated locally, and further, a large noise is generated. For this purpose, the area of the heat transfer plate 301 with the mounting groove 3011 is defined as a heat blocking area 3012, and the thermal contact surface 3013 is at least partially located in the heat blocking area 3012, that is, the heat blocking sheet 303 is mounted on one side of the heat blocking area 3012 by forming the mounting groove 3011, and at least a part of the thermal contact surface 3013 is on the other side of the heat blocking area 3012. Therefore, in the electric kettle with the heating tube 302 with higher power, the heat at the contact position of the heat transfer plate 301 and the heating tube 302 is not completely and directly transferred to the inner container 2 in a longitudinal mode, but is blocked by the heat blocking sheet 303, part of the heat is longitudinally transferred to the direction of the inner container 2 through the heat blocking sheet 303, and most of the rest of the heat is transversely transferred to other positions of the heat transfer plate 301 and then is longitudinally transferred to the inner container 2, so that when the heat transfer plate 301 is in thermal contact with the inner container 2, local and serious heat transfer is not easy to occur, but is transferred in a more uniform mode, and the fluid such as water and the like in the inner container 2 is not easy to generate bubbles and generate larger noise.

Referring to fig. 2-3, as another specific embodiment of the electric kettle provided by the present application, the thermal contact surface 3013 is located within the boundary of the heat blocking area 3012, so that the surfaces of the heat transfer plate 301 and the heat generating tube 302 that are in contact are all located in the heat blocking area 3012, and the heat blocking sheet 303 is disposed in the mounting groove 3011 on the side of the heat blocking area 3012 away from the heat generating tube 302, and after all the heat generated by the heat generating tube 302 is transferred to the heat transfer plate 301, all the heat is blocked by the heat blocking sheet 303 and is not directly transferred to the inner container 2 in the longitudinal direction, only part of the heat is transferred to the inner container 2 in the longitudinal direction through the heat blocking sheet 303, and most of the rest of the heat is transferred to the inner container 2 in the transverse direction after being transferred to other positions of the heat transfer plate 301, so that when the heat transfer plate 301 is in thermal contact with the inner container 2, the heat transfer plate is not prone to serious heat transfer, but is transferred in a more uniform manner, and the fluid such as water in the inner container 2 is not prone to generate bubbles, and is not prone to generate large noise.

Referring to fig. 2-3, as another specific embodiment of the electric kettle provided by the present application, the thickness of the heat blocking sheet 303 is the same as the depth of the mounting groove 3011, and the heat blocking sheet 303 is in heat conduction contact with the inner container 2, so that the positions of the inner container 2 corresponding to the heat blocking sheet 303 can also receive a certain amount of heat, and the heat receiving is kept close to the same heat receiving as other positions of the inner container 2, thereby further improving the uniformity of fluid such as water in the inner container 2 during heating, and not easily generating bubbles, i.e., not easily generating noise.

Referring to fig. 2-3, as another specific embodiment of the electric kettle provided by the present application, the heat transfer plate 301 is an aluminum plate, the heat blocking plate 303 is a stainless steel sheet or a carbon steel sheet, and the thermal conductivity of the aluminum plate is greater than the thermal conductivity of the stainless steel sheet or the carbon steel sheet, so that the heat blocking plate 303 can block partial heat of the heat transfer plate 301 from being transferred to the inner container 2 in a longitudinal manner, thereby preventing the heat of the heat transfer plate 301 and the heat generating tube 302 from being directly transferred to the inner container 2 in the longitudinal direction, so that the heat received by each part of the inner container 2 is relatively uniform, and the fluid such as water is not easy to generate bubbles, i.e., noise is not easy to generate.

Referring to fig. 4-5, as another embodiment of the electric kettle provided in the present application, the heating tube 302 is an arc tube, and the heating tube 302 can transfer heat to the inner container 2 through the heat transfer plate 301 and the heat blocking sheet 303 in a manner approaching to the circumference, so that the heat transferred to all parts of the inner container 2 is uniform, and the fluid such as water is not easy to generate bubbles, i.e., noise.

Referring to fig. 4, as another embodiment of the electric kettle provided by the present application, the heat resistant sheet 303 is a flat sheet shape, which is convenient for processing and installation.

Referring to fig. 6, as another specific embodiment of the electric kettle provided by the present application, a through hole 3031 is formed on the heat resistance sheet 303, so as to adjust the heat transfer speed of the heat resistance sheet 303, so as to meet the use requirement of the electric kettle.

Referring to fig. 7, as another embodiment of the electric kettle provided by the present application, a boss 3032 is disposed on the heat resistance sheet 303, so as to adjust the heat transfer speed of the heat resistance sheet 303, so as to meet the use requirement of the electric kettle.

Alternatively, the heat transfer plate 301 may be provided with the mounting groove 3011 by various methods such as stamping and casting, and then the inner container 2, the heat transfer plate 301, the heat blocking sheet 303, the heating tube 302, and the like are welded together by using flux solder.
