Abstract
Description
Technical Field

[0002] In the related art, during the operation of cooking appliances such as rice cookers and steamers, the food materials in the pot are heated to generate water vapor. In order to reduce the formation of condensed water on the inner wall of the pot cover when the water evaporated and spread in the pot contacts the relatively low-temperature pot cover, most of the existing cooking appliances adopt a heating mechanism arranged in the pot cover to heat the inner wall of the pot cover by using the heating mechanism, so that the temperature of the inner wall of the pot cover is kept consistent with the temperature in the pot, preventing the water vapor from contacting the inner wall of the pot cover to condense, and achieving a better cooking effect of the cooking appliance.

However, the cables on the pot cover and the electrodes of the heating source are mostly only connected by welding or using high-temperature resistant adhesive tapes. In the long-term high-temperature environment and during the process of opening and closing the pot cover multiple times, it is easy to cause the cables to be separated, loosened, offset, etc. from the electrodes of the heating source, and then cause poor contact between the cables and the electrodes of the heating source, affecting the stable heating of the inner wall of the pot cover and reducing the practicability and reliability of the cooking appliance.

[0030] In existing cooking appliances, most heating mechanisms use heating sources such as heating wires or heating films attached to the inner lid of the pot lid, and the electrodes of the heating source are powered to generate heat by connecting a cable to the heating source. However, the cable on the pot lid and the electrodes of the heating source are mostly connected only by welding or using a high-temperature resistant adhesive tape. In a long-term high-temperature environment and during the process of opening and closing the pot lid multiple times, it is easy for the cable and the electrodes of the heating source to become separated, loose, or offset, resulting in poor contact between the cable and the electrodes of the heating source, affecting the stable heating of the inner wall of the pot lid, and reducing the practicability and reliability of the cooking appliance. To address the above problems, the present utility model proposes a pot lid 100.
[0031] Please refer to Figures 1 to 6 , in an embodiment of the present utility model, the pot lid 100 includes a lid body 10, a heating substrate 30, and a fastener 50. The lid body 10 is used to open or cover the cooking utensil 200, and a connecting cable 11 is provided inside the lid body 10; the heating substrate 30 is connected to the lid body 10, the heating substrate 30 is provided with a heating element 31, the heating element 31 is provided with an electrode 311, and the electrode 311 is electrically connected to the connecting cable 11; the fastener 50 is provided on the lid body 10 and is arranged corresponding to the connection site of the electrode 311 and the connecting cable 11, and the fastener 50 is used to limit the relative movement of the electrode 311 and the connecting cable 11.
[0032] It can be understood that during the operation of the cooking appliance 1000, as the heating module in the cooking utensil 200 operates, the pot lid 100 can synchronously supply power to the heating element 31 through the connecting cable 11. The heating element 31 can be an electric heating wire, an electric heating rod, or an electric heating film made of materials such as graphene. The heating element 31 can convert electrical energy into heat energy and act on the heating substrate 30. The heating substrate 30 can be made of a material with certain heat conduction performance. Thus, the heat generated by the heating element 31 can be stably conducted to the entire heating substrate 30, realizing the heating function of the pot lid 100. Among them, the lid body 10 can have an inner surface for covering the cooking utensil 200 and a decorative outer surface opposite to the inner surface. The heating substrate 30 can be laminated with the inner surface of the lid body 10, so that when the pot lid 100 covers the cooking utensil 200, the heating substrate 30 can be exposed inside the cooking utensil 200. Therefore, when the food in the cooking utensil 200 is heated to generate water vapor, the temperature of the heating substrate 30 can reach the temperature of the water vapor at this time, thereby avoiding the condensation of the water vapor when it contacts the relatively low-temperature pot lid 100, effectively reducing the formation of condensed water on the heating substrate 30, and effectively avoiding the condensed water droplets from falling onto the food when the user opens the pot lid 100 to take out the food, ensuring the taste of the food after cooking, and improving the practicability and reliability of the cooking appliance 1000.
[0033] In the present application, the electrode 311 of the heating element 31 can be exposed on the surface of the heating substrate 30 facing the inner surface of the cover body 10, so that the connecting wire cable 11 in the pot cover 100 can be more conveniently connected to the electrode 311 on the surface of the heating substrate 30 to realize power supply and heating of the heating element 31. By providing the fastener 50 on the cover body 10, the fastener 50 can protrude on the inner surface of the cover body 10, and when the heating substrate 30 is installed on the cover body 10, the fastener 50 is directly opposite to the connection point of the electrode 311 of the heating element 31 and the connecting wire cable 11 on the heating substrate 30. In this way, the length of the partial structure of the fastener 50 protruding on the cover body 10 can be set corresponding to the distance between the cover body 10 and the heating substrate 30, so that the fastener 50 can press the electrode 311 of the heating element 31 and the connecting wire cable 11; or, the connection part of the electrode 311 of the heating element 31 and the connecting wire cable 11 can be cooperatively inserted with the fastener 50, so that the fastener 50 can form a connecting member between the electrode 311 of the heating element 31 and the connecting wire cable 11. Furthermore, under the action of the fastener 50, the contact friction force between the electrode 311 of the heating element 31 and the connecting wire cable 11 can be increased, or the electrode 311 of the heating element 31 and the connecting wire cable 11 can be inserted and fixed by the fastener 50, effectively preventing the relative movement between the electrode 311 of the heating element 31 and the connecting wire cable 11, avoiding the pulling of the connecting wire cable 11 by the user when opening and closing the pot cover 100 multiple times, which may cause the separation of the connecting wire cable 11 from the electrode 311 of the heating element 31 with a certain probability, effectively improving the connection stability and reliability between the heating element 31 and the connecting wire cable 11, ensuring the stable operation of the cooking appliance 1000, and further improving the structural stability and reliability of the pot cover 100.
[0034] In addition, when the heating substrate 30 is made of a glass material such as borosilicate glass, the heating element 31 can be formed by coating a conductive heating coating on the heating substrate 30. Since the heating substrate 30 made of glass material has poor high-temperature resistance, the electrodes of the heating element 31 can be fixed to the connection cable 11 by gluing, avoiding the welding of the electrodes 311 of the heating element 31 and the connection cable 11 on the heating substrate 30, which may cause the heating substrate 30 to crack with a certain probability, and ensuring the overall structural stability of the pot lid 100. Inside the cooking appliance 1000, the pot lid 100 can be installed and connected to the cooking pot 200 through a hinge member. At this time, the connection cable 11 can pass through the hinge member to connect the heating element 31 and the control system inside the cooking pot 200. Therefore, when the pot lid 100 opens and closes on the cooking pot 200, it is likely to generate a certain pulling force on the connection cable 11. Therefore, by arranging the fastener 50 inside the lid body 10 to fix the electrodes 311 of the heating element 31 and the connection cable 11, restricting the relative movement of the electrodes 311 of the heating element 31 and the connection cable 11, it can effectively prevent the connection cable 11 from being pulled when the cooking appliance 1000 opens the pot lid 100, resulting in the damage of the gluing site between the connection cable 11 and the electrodes 311, so that the electrodes 311 of the heating element 31 and the connection cable 11 can achieve a more stable and reliable connection, ensuring the stable heating of the heating substrate 30 inside the pot lid 100, and further improving the structural stability and reliability of the pot lid 100.
[0035] The technical solution of the present utility model can utilize the fastener 50 protruding on the inner surface of the lid body 10 facing the heating substrate 30 by arranging the fastener 50 on the lid body 10. By arranging the fastener 50 corresponding to the connection sites of the electrodes 311 of the heating element 31 and the connection cable 11, after the heating substrate 30 is installed on the lid body 10, the fastener 50 can be used to press the electrodes 311 of the heating element 31 and the connection cable 11, or the fastener 50 can be inserted to fix the electrodes 311 of the heating element 31 and the connection cable 11. Furthermore, under the action of the fastener 50, the relative movement of the electrodes 311 of the heating element 31 and the connection cable 11 can be effectively prevented, realizing the stable electrical connection between the electrodes 311 of the heating element 31 and the connection cable 11, ensuring the stable operation of the cooking appliance 1000, and effectively improving the structural stability and reliability of the pot lid 100.
[0036] Refer to Figure 2 and Figure 3 In an embodiment of the present utility model, a receiving cavity 131 is provided inside the lid body 10, and an avoidance hole 133 communicating with the receiving cavity 131 is provided on the surface of the lid body 10 facing the heating substrate 30. The fastener 50 is telescopically arranged in the receiving cavity 131, and a part of the structure of the fastener 50 passes through the avoidance hole 133 to press and fix the electrode 311 and the connection cable 11.
[0037] In this embodiment, by providing a receiving cavity 131 in the cover body 10, the fastener 50 can be installed in the receiving cavity 131 to achieve the installation and fixation of the fastener 50 on the cover body 10, effectively preventing the fastener 50 from shifting on the cover body 10, which may otherwise cause the fastener 50 to become detached from the fixation of the electrode 311 of the heating element 31 and the connecting wire harness 11 with a certain probability, further improving the overall structural stability and reliability of the pot lid 100. Among them, the fastener 50 can be configured as a structure with a certain elasticity, or can be a mechanism such as an electric push rod, so that the fastener 50 can pass a part of the structure through the avoidance hole 133 on the inner surface of the cover body 10 and abut against the connection point of the electrode 311 of the heating element 31 and the connecting wire harness 11. At this time, when the fastener 50 presses against the electrode 311 of the heating element 31 and the connecting wire harness 11, a certain elastic deformation can occur, so that the elastic action of the fastener 50 can be used to maintain the abutting force of the fastener 50 on the electrode 311 of the heating element 31 and the connecting wire harness 11; or the telescopic length of the fastener 50 can be stably maintained under the action of the electric push rod to ensure the pressing force on the electrode 311 of the heating element 31 and the connecting wire harness 11. In this way, the connection stability and reliability between the electrode 311 of the heating element 31 and the connecting wire harness 11 can be better utilized by the fastener 50, ensuring the stable heating of the heating substrate 30, better reducing the generation of condensed water on the pot lid 100, and further improving the practicality and reliability of the pot lid 100.
[0038] Refer to Figure 2 , in an embodiment of the present utility model, the material of the fastener 50 is an elastic colloid material.
[0039] In this embodiment, the fastener 50 can be made of an elastic colloid material such as heat-resistant insulating rubber or heat-resistant insulating silica gel with a certain elasticity, so that the fastener 50 can form a better overall structure, facilitating the installation of the fastener 50 on the cover body 10. At the same time, making the fastener 50 from an elastic colloid material can endow the fastener 50 with a relatively stable elastic force, which is beneficial to better using the elastic deformation of the fastener 50 to stably press against the electrode 311 of the heating element 31 and the connecting wire harness 11. Moreover, the contact surface of the fastener 50 can have a certain flexibility, enabling the fastener 50 to better fit and abut against the electrode 311 of the heating element 31 and the connecting wire harness 11, reducing the probability that the relatively large pressing force of the fastener 50 may damage the electrode 311 of the heating element 31 and the connecting wire harness 11, and further improving the structural stability and reliability of the pot lid 100.
[0040] Refer to Figure 3, in an embodiment of the present utility model, the fastener 50 includes a pressing slider 51 and an elastic member 53. The pressing slider 51 is disposed in the accommodating cavity 131 in a vertically movable manner. A part of the structure of the pressing slider 51 passes through the avoidance hole 133 to press against the fixed electrode 311 and the connecting wire cable 11; the elastic member 53 connects the pressing slider 51 and the inner wall of the cavity of the accommodating cavity 131.
[0041] In this embodiment, the elastic member 53 can be a structure with certain elasticity such as a spring or a reed, and the pressing slider 51 can be made of a material with certain heat resistance and insulation. The fastener 50 can use the elastic member 53 to connect the top of the cavity of the accommodating cavity 131 and the pressing slider 51 to realize the elastic lifting movement of the pressing slider 51 in the accommodating cavity 131. Furthermore, during the assembly process of the pot lid 100, when the connection point of the electrode 311 of the heating element 31 and the connecting wire cable 11 contacts the pressing slider 51, a certain acting force can be applied to the pressing slider 51, so that the pressing slider 51 squeezes the elastic member 53 to generate a certain elastic deformation. Then, after the pot lid 100 is assembled, the elastic acting force of the elastic member 53 can be used to drive the pressing slider 51 to firmly press the electrode 311 of the heating element 31 and the connecting wire cable 11, better improving the connection stability and reliability between the electrode 311 of the heating element 31 and the connecting wire cable 11, and further improving the overall structural stability and reliability of the pot lid 100.
[0042] Refer to Figures 1 to 3 , in an embodiment of the present utility model, the lid body 10 includes an outer lid 15 and an inner lid 13. The outer lid 15 surrounds the inner lid 13. The inner lid 13 is disposed at an interval from the heating substrate 30. The inner lid 13 is provided with an avoidance hole 133. An installation platform 135 is further provided in the lid body 10. The installation platform 135 is connected to the side of the inner lid 13 facing away from the heating substrate 30 and encloses an accommodating cavity 131 with the inner lid 13.
[0043] In this embodiment, the lid body 10 can include the inner lid 13 for opening and closing the cookware 200 and the decorative outer lid 15 surrounding the inner lid 13. At this time, the heating substrate 30 can be disposed below the inner lid 13 and the heating substrate 30 is disposed at an interval from the inner lid 13 to avoid the heat on the heating substrate 30 being transferred to the inner lid 13, facilitating the user's operation of the cooking appliance 1000. The heating substrate 30 can be snap-fitted and fixed on the inner lid 13, or a snap or clip can be provided at the connection position between the inner lid 13 and the outer lid 15 to fix the heating substrate 30, ensuring the installation and fixation of the heating substrate 30 on the lid body 10 and further improving the structural stability and reliability of the pot lid 100.
[0044] Among them, by providing a mounting platform 135 on the side of the inner cover 13 facing away from the heating substrate 30, the mounting platform 135 can be arranged in a cover structure, so that a certain groove structure is formed inside the mounting platform 135. Furthermore, the mounting platform 135 and the inner cover 13 can enclose to form a receiving cavity 131, realizing the installation and fixation of the fastener 50. By providing the mounting platform 135 on the inner cover 13 to form the receiving cavity 131, a space for accommodating and installing the fastener 50 can be formed locally on the inner cover 13, without the need to make the inner cover 13 have a relatively large thickness structure, which is beneficial to better simplify the overall structure of the cover body 10 and facilitate the miniaturization design of the pot lid 100, further improving the practicability and reliability of the pot lid 100.
[0045] Refer to Figure 2 and Figure 3 , in an embodiment of the present utility model, an installation opening 1351 is provided on one side of the mounting platform 135. And / or, the mounting platform 135 is detachably connected to the inner cover 13. And / or, a mounting groove is provided on the side of the inner cover 13 facing away from the heating substrate 30, and the mounting platform 135 covers the mounting groove.
[0046] In this embodiment, the cover body 10 can provide an installation opening 1351 on one side of the mounting platform 135. The size of the installation opening 1351 can be set corresponding to the size of the fastener 50 when it is compressed to the maximum deformation amount, so that the fastener 50 can be squeezed into the receiving cavity 131 through compression from the installation opening 1351 for installation. By providing the installation opening 1351 for assembly, the mounting platform 135 and the inner cover 13 can be designed as an integral structure, which is beneficial to better improve the overall structural strength of the inner cover 13 and the structural stability and reliability of the pot lid 100.
[0047] In addition, the cover body 10 can also make the mounting platform 135 be detachably arranged on the inner cover 13 by bolts or buckles, so that the fastener 50 can be installed into the receiving cavity 131 by disassembling and assembling the mounting platform during the assembly process, which is beneficial to better improve the assembly convenience of the pot lid 100 and further improve the practicability and reliability of the pot lid 100.
[0048] By providing a mounting groove on the side of the inner cover 13 facing away from the heating substrate 30, a groove structure cooperating with the mounting platform 135 can be provided on the inner cover 13. By using the mounting platform 135 to cover the mounting groove to form the receiving cavity 131, the fastener 50 can be more stably arranged in the inner cover 13, better realizing the miniaturization design of the cover body 10 and further improving the practicability and reliability of the pot lid 100.

The fastener 50 is provided with a plugging column 55, and the plugging column 55 passes through the first fixing hole 111 and the second fixing hole 3111 and is plugged into the positioning hole 33.
[0050] In this embodiment, the cover body 10 can be provided with a power connection end plate with a certain area at the end of the power connection cable 11, so that the pot cover 100 can realize the electrical connection between the power connection cable 11 and the electrode 311 by using the power connection end plate to contact the electrode 311 of the heating element 31. By providing a through first fixing hole 111 on the power connection end plate, correspondingly providing a through second fixing hole 3111 on the electrode 311, and simultaneously providing a positioning hole 33 at the connection site of the heating substrate 30 corresponding to the power connection end plate and the electrode 311, the first fixing hole 111, the second fixing hole 3111 and the positioning hole 33 can be made to communicate after assembly.
