Description

Technical Field

[0001] This application relates to the technical field of multi-functional electric cookers, and more particularly to a waterproof structure. Background Technology

[0002] Multifunctional electric cookers, integrating cooking, steaming, and stewing functions, have gradually become common appliances in modern kitchens. However, in actual use, issues with the seal between the pot body and the inner pot can easily allow liquid to seep into the main body. Alternatively, when cleaning the pot, liquid can easily flow into the interior through the ventilation holes at the bottom. Either way, this can easily cause short circuits or damage to components, severely impacting lifespan and safety. Therefore, there is an urgent need for those skilled in the art to develop a new waterproof structure and a multifunctional electric cooker to meet diverse practical needs. Utility Model Content

[0003] The main objective of this application is to provide a waterproof structure that addresses the aforementioned technical problems.

[0004] A waterproof structure includes a pot body and an inner liner disposed on the pot body, and further includes a connecting sealing ring disposed between the upper side of the pot body and the upper side of the inner liner.

[0005] The lower side of the inside of the pot body is provided with an upwardly protruding column located below the inner liner, and the protruding column has vertical heat dissipation holes along its axial direction.

[0006] As described above, the waterproof structure has a hook portion that is folded downward and located on the upper side of the inner liner and is located on the upper side of the pot body. An annular upper groove is provided on the hook portion.

[0007] The upper side of the pot body is provided with an annular limiting step;

[0008] The connecting sealing ring is provided with an annular upper protrusion that can be adapted to and connected with the annular upper groove, and is also provided with an annular adaptation limiting step that can be adapted to and connected with the annular limiting step.

[0009] As described above, the waterproof structure further includes a pot-mouth sealing ring that is detachably connected to the hook portion and the outside of the connecting sealing ring.

[0010] As described above, in the waterproof structure, the connecting sealing ring is also provided with an annular inner groove, which is located between the annular upper protrusion and the annular adapter limiting step;

[0011] The pot opening sealing ring is provided with an annular protrusion that can be adapted to connect within the annular inner groove, and an annular adaptation groove located on the upper side of the annular protrusion for adapting to connect the hook portion and the annular upper protrusion.

[0012] As described above, the waterproof structure also includes a flow guide nozzle on the pot opening sealing ring.

[0013] In the waterproof structure described above, both the connecting sealing ring and the pot opening sealing ring are made of silicone.

[0014] This application also provides a multi-functional electric cooker, including the waterproof structure described above.

[0015] Compared with the prior art, the above application has the following advantages:

[0016] This application incorporates raised pillars inside the pot body with vertical heat dissipation holes. These holes not only dissipate heat but also effectively raise the height of existing heat dissipation holes, thus preventing the risk of short circuits caused by water accumulation at the bottom during cleaning. Furthermore, by installing a sealing ring between the pot body and the inner pot, liquid is effectively prevented from seeping into the interior through the gap between the pot body and the inner pot, achieving a comprehensive waterproof effect from top to bottom. This further enhances the waterproof safety performance of existing multi-functional electric cookers. Attached Figure Description

[0027] like Figures 1 to 6 As shown, a waterproof structure includes a pot body 100 and an inner liner 200 disposed on the pot body 100. The lower side of the interior of the pot body 100 is provided with an upwardly protruding column 11 located below the inner liner 200. The protruding column 11 is provided with vertical heat dissipation holes 111 along its axial direction.

[0028] The waterproof structure also includes a connecting sealing ring 300 disposed between the upper side of the pot body 100 and the upper side of the inner liner 200.

[0029] The waterproof structure of this application features a raised column 11 inside the pot body 100, with vertical heat dissipation holes 111 on the raised column 11. This allows heat to be dissipated through the vertical heat dissipation holes 111, and also effectively raises the position of the existing heat dissipation holes, thereby effectively preventing the risk of short circuits caused by water accumulation at the bottom during cleaning. In addition, by setting a connecting sealing ring 300 between the pot body 100 and the inner pot 200, liquid is effectively prevented from seeping into the interior from the gap between the pot body 100 and the inner pot 200, thus achieving a comprehensive waterproof effect from top to bottom, further improving the waterproof safety performance of existing multi-functional electric cookers.

[0030] Furthermore, the upper edge of the inner liner 200 is provided with a hook portion 21 that is folded downward and located on the upper side of the pot body 100, and an annular upper groove 22 is provided on the hook portion 21.

[0031] The upper interior of the pot body 100 is provided with an annular limiting step 12;

[0032] The connecting sealing ring 300 is provided with an annular upper protrusion 31 that can be adapted to and connected with the annular upper groove 22, and is also provided with an annular adaptable limiting step 32 that can be adapted to and connected with the annular limiting step 12.

[0033] The sealing ring 300 of this application achieves a stable engagement between the sealing ring 300 and the inner liner 200 through the cooperation of the annular upper protrusion 31 and the annular upper groove 22. In addition, the cooperation of the annular adapter limiting step 32 and the annular limiting step 12 ensures that the sealing ring 300 is firmly positioned on the pot body 100, thereby effectively preventing displacement or falling off during the assembly process and improving the sealing reliability and assembly convenience of the overall structure.

[0034] Furthermore, the waterproof structure also includes a pot-mouth sealing ring 400 that is detachably connected to the outside of the hook portion 21 and the connecting sealing ring 300.

[0035] The connecting sealing ring 300 is also provided with an annular inner groove 33, which is located between the annular upper protrusion 31 and the annular adapter limiting step 32.

[0036] The pot opening sealing ring 400 is provided with an annular protrusion 41 that can be adapted to connect within the annular inner groove 33, and an annular fitting groove 42 located on the upper side of the annular protrusion 41 for adapting and connecting the hook portion 21 and the annular upper protrusion 31. The purpose is to enable the pot opening sealing ring 400 to be detachable, facilitating subsequent disassembly, cleaning, and replacement, thereby improving the product's maintenance convenience and service life.

[0037] Furthermore, the pot opening sealing ring 400 is also provided with a guide nozzle 43. The design of the guide nozzle 43 in this application is specifically to facilitate the discharge of soup or residual liquid inside the inner pot 200, and to prevent overflow and contamination of the pot body 100 when pouring out food or soup.

[0038] Furthermore, both the connecting sealing ring 300 and the pot opening sealing ring 400 are made of silicone. The advantage of silicone is that it has good elasticity and sealing properties, enabling a tight fit between the pot body and lid through compression deformation when closed, effectively preventing steam leakage, and ensuring safe use through its outstanding stability.

[0039] This application also provides a multi-functional electric cooker, including the waterproof structure described above, and further including a lid 500, a heating plate 600, a temperature sensor 700, a PCB circuit board (not shown in the figure), a power input port 800, and a control display screen 900.

[0040] The pot lid 500 covers the pot opening sealing ring 400 and is equipped with an exhaust valve 51. The heating plate 600 is located on the lower side of the inner pot 200 and is electrically connected to the PCB circuit board. The temperature sensor 700 is located on the lower side of the heating plate 600 and is electrically connected to the PCB circuit board. The PCB circuit board is located below the temperature sensor 700. The power input port 800 is located on the lower side of the pot body 100 and is electrically connected to the PCB circuit board for connecting an external power source. The control display screen 900 is located on the outer periphery of the pot body 100 and is electrically connected to the PCB circuit board for setting cooking modes and displaying working status.

[0041] This multi-functional electric cooker enables electric heating cooking and allows for precise setting of cooking modes via a control display screen 900. It also monitors temperature changes inside the pot in real time, ensuring that food is heated as needed at different stages, thus improving cooking results and safety.

[0042] Furthermore, the upper side of the pot opening sealing ring 400 is provided with an annular connecting recess 44;

[0043] The lower edge of the pot lid 500 is provided with an adapter ring portion 52 that can be adapted to connect with the annular connection recess 34.

[0044] When the lid 500 is closed, the fitting ring part 52 fits into the annular connecting recess 44, achieving a tight seal between the lid 500 and the sealing ring 400 at the pot opening, effectively preventing steam leakage during cooking.
