[0001] The utility model relates to the technical field of household appliances, in particular to a water-proof electric stew pot. Background Art

[0002] The water-proof electric stew pot is a kitchen appliance commonly used in modern families. It uses boiling hot water to gently stew the food in the inner pot. The heat energy penetrates into the food in the inner pot through water as a medium, so that the nutritional components of the stew will not be destroyed due to overheating.

[0003] When the existing water-proof electric stew pot is stewing, the bottom of the water tank is heated centrally, so that a large number of bubbles are generated in the water tank. These bubbles will continue to rise and burst, which will not only produce gurgling noises, but also push the stew pot components to shake, produce collision sounds, and even cause the soup in the stew pot to spill.

[0004] How to develop a water-proof electric stew pot that can reduce the noise generated in the water tank when cooking soup and prevent the soup in the ceramic inner pot from spilling has become a technical problem that needs to be urgently solved by technical personnel in this field.

[0012] Preferably, when the heating component adopts the heating belt, the annularly arranged heating belt abuts against the outer side wall of the water tank.

[0013] Preferably, when the heating component adopts one PTC heating element, the upper surface of the PTC heating element abuts against the lower surface of the bottom of the water tank, and the PTC heating element is located below the cavity formed by the water tank and the ceramic inner tank.

[0014] Preferably, when the heating component adopts a plurality of the PTC heating elements, the upper surfaces of the plurality of the PTC heating elements abut against the lower surface of the bottom of the water tank, and the plurality of the PTC heating elements are evenly distributed in a ring shape along the bottom of the water tank.

[0015] Preferably, the inner diameter of the plurality of PTC heating elements arranged in a ring is not less than the outer diameter of the bottom of the ceramic inner tank.

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] like Figure 1-11 As shown, a water-proof electric stew pot comprises an upper cover 1, a base 4, a water tank 5, a ceramic inner cover 6, a ceramic inner pot 7 and a heating assembly, wherein the upper cover 1 covers the upper opening of the water tank 5, an internal threaded column is provided on the lower surface of the water tank 5, and a support column on the inner surface of the base 4 is fixedly connected to the internal threaded column by screws;

[0037] The edge of the ceramic inner cover 6 is provided with a groove, the upper end opening of the ceramic inner liner 7 is provided with a boss, the ceramic inner cover 6 covers the ceramic inner liner 7, and the groove cooperates with the boss, and the ceramic inner liner 7 is placed inside the water tank 5;

[0038] The heating assembly is installed on the inner side, outer side wall or lower surface of the bottom of the water tank 5;

[0039] The edge of the ceramic inner cover 6 is provided with a groove, and the upper end opening of the ceramic inner pot 7 is provided with a boss. The ceramic inner cover 6 covers the ceramic inner pot 7, and the groove cooperates with the boss. The ceramic inner pot 7 is placed inside the water tank 5. The ceramic inner cover and the ceramic inner pot cooperate with each other in the groove and the boss, so that the ceramic inner cover and the ceramic inner pot can be tightly connected, so that water vapor will not enter the ceramic inner pot, and the loss of nutrition of the stew can be prevented. At the same time, it can effectively ensure that the soup inside will not spill during the stewing operation, and can further achieve the effect of heat preservation;

[0040] The heating component is installed on the inner part, outer wall or lower surface of the bottom of the water tank 5, so that when the heating component heats the water in the water tank, the bubbles generated can emerge from the cavity formed by the ceramic inner pot and the inner wall of the water tank, thereby preventing the bubbles generated during local heating from pushing the ceramic inner pot to shake and collide with the water tank to generate noise. Furthermore, when small bubbles burst, the noise generated is smaller than that generated by large bubbles generated by local heating, thereby improving the user experience when stewing soups.

[0041] Specifically, it also includes an outer shell 2, which is covered on the outer circumferential surface of the water tank 5, and the opening of the water tank 5 is sealed and connected to the step surface at the upper end opening of the outer shell 2, and the lower end opening of the outer shell 2 is abutted against the base 4; a double-layer setting of the outer shell is arranged on the outer circumferential surface of the water tank, which further ensures the thermal insulation performance of the water tank, and at the same time, it can also reduce the propagation of noise to the outside, thereby achieving noise reduction from the noise propagation path.

[0042] Specifically, the heating component uses a heating belt 8, one or more PTC heating elements 9, a brazed heating tube 10 or an empty burning tube 11. When the specific structure is set, any one of the structures is used alone to heat the water in the water tank.

[0043] Embodiment 1

[0044] like Figure 2-4 As shown, when the heating component adopts the heating belt 8, the annularly arranged heating belt abuts against the outer side wall of the water tank 5, and the heating belt is annularly arranged on the side wall of the water tank. By heating the side wall of the water tank, the water in the water tank is further heated, so that bubbles formed by water vapor generated by the heated water are evenly distributed around the ceramic inner pot, reducing the noise generated when the bubbles burst, and reducing the impact on the ceramic inner pot, so that the ceramic inner pot can be heated smoothly in the water tank, reducing the noise generated by the ceramic inner pot colliding with the bottom of the water tank due to the bursting of bubbles when stewing soup.

[0045] Embodiment 2

[0046] like Figure 5 As shown, when the heating component adopts one PTC heater 9, the upper surface of the PTC heater 9 abuts against the lower surface of the bottom of the water tank 5, and the PTC heater 9 is located below the cavity formed by the water tank 5 and the ceramic inner tank 7. The PTC heater is offset at the bottom of the water tank to avoid direct heating of the bottom of the ceramic inner tank by the PTC heater. Furthermore, when the water inside the water tank is heated, the bubbles generated will not cause the ceramic inner tank to shake, thereby greatly reducing the noise during stewing.

[0047] Embodiment 3

[0048] like Figure 6-8 As shown, when the heating component adopts multiple PTC heaters 9, the upper surfaces of two of the PTC heaters are in contact with the lower surface of the bottom of the water tank 5, and the two PTC heaters are evenly distributed in a ring along the edge of the bottom of the water tank 5, and the angular interval between the two PTC heaters is 180°. Furthermore, the inner diameter of the ring formed between the two opposite surfaces of the two annularly arranged PTC heaters 9 is not less than the outer diameter of the bottom of the ceramic inner tank 7. The PTC heaters are arranged separately and dispersed on the lower surface of the water tank for heating, so that bubbles generated during heating emerge from the cavity formed by the outer wall of the water tank and the ceramic inner tank, avoiding local concentrated heating at the bottom of the ceramic inner tank, so that the generated bubbles push the ceramic inner tank to move and make noise. Furthermore, the dispersed heating method can also reduce the volume of the bubbles and reduce the noise generated when the bubbles burst.

[0049] Embodiment 4

[0050] like Figure 9-10 As shown, when the heating component adopts the brazed heating tube 10, the brazed heating tube 10 is arranged in a ring shape on the lower surface of the bottom of the water tank 5, and the brazed heating tube 10 abuts against the lower surface of the water tank 5, and the inner diameter of the brazed heating tube 10 is not less than the bottom outer diameter of the ceramic inner tank 7. The brazed heating tube is heated on the lower surface of the water tank, and the generated bubbles are evenly emitted from the cavity formed between the ceramic inner tank and the inner wall of the water tank, so that there are bubbles outside the side wall of the ceramic inner tank. Furthermore, the generated bubbles will not cause the ceramic inner tank to shake in the water tank and generate noise during the rising process, and the noise generated when the bubbles burst is small.

[0051] Embodiment 5

[0052] like Fig.11 As shown, when the heating component adopts the empty burning tube 11, the empty burning tube is arranged in a ring inside the water tank 5, and the inner diameter of the empty burning tube is larger than the outer diameter of the ceramic inner liner 7. Specifically, the connection between the empty burning tube and the water tank is sealed to prevent the water in the water tank from overflowing to the inside of the shell and causing danger. Furthermore, the empty burning tube is installed inside the water tank to directly perform annular heating on the water in the water tank, and the inner diameter of the empty burning tube is larger than the outer diameter of the ceramic inner liner 7, so that the bubbles generated during heating are evenly dispersed around the ceramic inner liner, avoiding the disturbance of the ceramic inner liner by the bubbles and reducing noise.

[0053] In addition, it also includes a PLC controller and a power interface. The PLC controller is installed on the outer wall of the shell or the water tank, and the power interface is installed on the outer wall of the base. The heating component and the power interface are electrically connected to the PLC controller. The control program is known and can be implemented by those skilled in the art, so it will not be repeated here.

[0054] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0055] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
