Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, specifically a cooking utensil. Background Technology

[0002] In modern life, various cooking appliances in the kitchen appliance sector are widely used by consumers. In the structure of existing cooking appliances such as rice cookers, the connection between the lid and the lid handle is usually a fixed connection to ensure the strength of the connection between the two.

[0003] However, during the manufacturing process of cooking utensils, there may be certain manufacturing errors in the sealing surface of the pot body and the fitting surface of the lid edge, or the pot body and lid may deform during long-term use. If a fixed connection is used directly between the lid and the lid handle, when the lid is closed, there may be areas where the fit is too tight, causing the lid to deform, or areas where the fit is loose, forming gaps. This can lead to problems such as uncontrolled steam escape and temperature fluctuations inside the pot, affecting the cooking quality. Utility Model Content

[0004] To address the above problems, this utility model provides a cooking utensil that allows the lid handle to open and close the lid on the pot body without limiting the axial position of the lid.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Figure 1 This is a structural front view of a cooking appliance 100 provided in this embodiment, with reference to... Figure 1 The cooking appliance 100 includes a heating base 1, a pot body 2, a pot lid 3, and a pot lid opening / closing part 4. The pot body 2 is made of a single piece of metal and is housed within the heating base 1, which supplies heat to the pot body 1. The pot lid 3 is also made of a single piece of metal and is positioned on top of the pot body 2. The outer edge of the pot lid 3 directly abuts against the outer edge of the top of the pot body 2 to achieve a seal between the pot body 2 and the pot lid 3. One end of the pot lid opening / closing part 4 is rotatably connected to the heating base 1, and the other end extends to the top of the pot lid 3 and connects to it. The rotational stroke of the pot lid opening / closing part 4 includes a first position where the pot lid 3 is pressed against the pot body 2, and a second position where the pot lid 3 is separated from the pot body 2.

[0027] During cooking, the food is placed within the enclosed space formed by the pot body 2 and the lid 3. The safety of the materials in direct or indirect contact with the food within this space affects the hygiene and health of the food. In traditional cooking utensils, silicone pads or plastic components are often placed inside or between the pot body 2 and the lid 3. Water vapor may condense and trap water in the gaps of these components, leading to the growth of mold and bacteria that can contaminate the food. Furthermore, in long-term high-temperature and high-humidity environments and repeated heating cycles, substandard silicone or plastic may release harmful substances that migrate to the food. Therefore, in this embodiment, both the pot body 2 and the lid 3 are made of a single piece of metal, ensuring that the food remains in a safe and clean metal environment throughout the cooking process, thus achieving "zero plasticization" cooking and providing users with healthier food protection and a superior cooking experience.

[0028] Traditional cooking utensils typically have a silicone sealing ring on the inner edge of the lid 3 to ensure a tight seal between the lid 3 and the pot body 2 and to prolong the retention time of steam inside the pot. However, in this embodiment, the lid 3 is made of a single piece of metal, eliminating the need for the silicone sealing ring. To prevent steam from leaking too quickly between the pot body 2 and the lid 3, and to prevent drastic temperature fluctuations inside the pot from affecting the cooking effect, this embodiment, in addition to using a structure where the outer edge of the lid 3 directly abuts against the top outer edge of the pot body 2 to achieve a seal, further includes an annular water seal groove 21 on the top outer edge of the pot body 2. When the lid 3 is in the first position pressing against the pot body 2, the outer edge of the lid 3 is precisely embedded and abuts against the annular water seal groove 21. The sealing principle of the annular water seal groove 21 is as follows: When the cooking appliance 100 starts operating, the heating base 1 heats the pot body 2, and the water pre-added to the pot body 2 is converted into steam. As the steam rises, it comes into contact with the relatively cool metal lid 3 and quickly condenses into liquid water. This condensate flows naturally along the inner wall of the lid 3 to the annular water seal groove 21. As the condensate gradually accumulates in the groove, it forms a uniform water film at the contact point between the pot body 2 and the lid 3. Utilizing the surface tension of the condensate, this water film tightly fills the tiny gaps between them, forming a highly efficient sealing barrier, thus preventing steam from escaping between the pot body 2 and the lid 3. Through the annular water seal groove 21, even without a traditional silicone sealing ring, the temperature, humidity, and pressure inside the pot body 2 of the cooking appliance 100 can still be maintained within a stable range, providing a suitable cooking environment for the food and ensuring optimal cooking results.

[0029] More specifically, refer to Figure 2The annular water seal groove 21 includes a first bent section and a second bent section 21B arranged radially outward. Specifically, in the radially outward direction, the first bent section 21A extends downward at an angle, and the second bent section 21B extends upward at an angle. The outer edge of the lid 3 abuts against the top of the first bent section 21A. When the lid 3 covers the opening of the pot body 2, to ensure that the outer edge of the lid 3 can fit and abut against the top of the pot body 2, the outer edge of the lid 3 has a third bent section 32 extending parallel to the first bent section 21A. The third bent section 32 abuts against the first bent section 21A in a surface contact manner.

[0030] Regarding the structure of the multiple bending sections mentioned above, on the one hand, the downward-sloping extension of the first bending section 21A creates a smooth guide slope on the top of the pot body 2, facilitating the flow of condensed water into the annular water seal groove 21 by gravity. When the user moves the lid 3 to the first position against the pot body 2, the outer edge of the lid 3 automatically slides along the guide slope to the top of the first bending section 21A, i.e., the contact position between the lid 3 and the pot body 2. This eliminates the need for the user to manually adjust the alignment of the lid 3 edge with the annular water seal groove 21, effectively simplifying the operation. Simultaneously, the design of the first bending section 21A ensures that when the lid 3 is in the first position, the third bending section 32 on the outer edge of the lid 3 automatically fits against the guide slope of the first bending section 21A on the top of the pot body 2, achieving a high degree of tightness through surface contact, thus laying the foundation for a water film seal between the lid 3 and the pot body 2. Preferably, the width of the first bending section 21A, i.e., the width of the inner side of the annular water seal groove 21 used to absorb concentricity, is 2-3.5 mm. This size range ensures sufficient fit between the first bending section 21A and the third bending section 32. Even if there is a certain degree of concentricity deficiency between the lid 3 and the pot body 2 during processing, this width can absorb the processing error. On the other hand, the upward-sloping design of the second bending section 21B provides sufficient depth for the annular water seal groove 21 to store enough condensate to meet the water film formation conditions required for sealing, and effectively prevents the condensate in the annular water seal groove 21 from overflowing to the outside of the pot body 2, avoiding the normal use of the cooking appliance 100 due to condensate leakage. In addition, the first bending section 21A and the second bending section 21B are formed from a single piece of metal from the pot body 2, and there are no seams in the annular water seal groove 21 formed by the two, thus avoiding the generation of unsanitary corners. When cleaning, users only need to wipe or rinse the inner wall of the tank to quickly and thoroughly remove residual stains, greatly reducing the difficulty of cleaning and further improving the user experience and hygiene safety of the product.

[0031] In this embodiment, the opening and closing of the pot lid 3 of the cooking appliance 100 is achieved by rotating the pot lid opening and closing part 4, that is, the pot lid 3 is rotated to a first position and a second position relative to the pot body 2 by the pot lid opening and closing part 4. The first position is the position when the pot lid 3 is fully closed, i.e. Figure 2The second position, shown in the diagram, is when the lid 3 is fully open; it is not shown in the diagram. (Reference) Figure 2 and Figure 3 The lid opening / closing part 4 includes a hinge shaft 41, a locking mechanism 42, and an unlocking trigger mechanism 43. The lid opening / closing part 4 is rotatably connected to the heating base 1 via the hinge shaft 41. The locking mechanism 42 is located on the same side of the pot body 2 as the hinge shaft 41, configured to lock the lid opening / closing part 4 in a first position. The unlocking trigger mechanism 43 is connected to the locking mechanism 42 via an intermediate transmission component and is located at the end of the lid opening / closing part 4 away from the hinge shaft 41. The user can unlock the lid opening / closing part 4 from the first position by operating the unlocking trigger mechanism 43, and rotate the lid 3 to a second position. To make the rotation of the lid opening / closing part 4 and the lid 3 from the first position to the second position more convenient and efficient, the lid opening / closing part 4 includes a torsion spring 44 connected to the hinge shaft 41, allowing the lid opening / closing part 4 to elastically return to the second position.

[0032] More specifically, the lid opening and closing part 4 also includes a lid handle 46, which is located on the top of the lid 3 and connected to the lid 3. The lid handle 46 is rotatably connected to the heating base 1 by means of a hinge shaft 41. The rotation stroke of the lid handle 46 includes a first position where the lid 3 is pressed against the pot body 2, and a second position where the lid 3 is separated from the pot body 2. The unlocking trigger mechanism 43 is located at the end of the lid handle 46 away from the hinge shaft 41.

[0033] The unlocking trigger mechanism 43 is a hook 431 extending along the length of the lid opening / closing portion 4. The middle part of the hook 431 is rotatably connected to the lid opening / closing portion 4. The end of the hook 431 away from the hinge axis 41 is configured as a pressable and deformable hook button 432. The end of the hook 431 near the hinge axis 41 is connected to the locking mechanism 42. (Reference) Figure 2 and Figure 3 The hook rod 431, located near the hinge axis 41 along its length, is pivotally connected to the lid handle 46, also near the hinge axis 41, via a hook rod button axis 433. When the user presses the hook rod button 432, the hook rod 431 can rotate about the hook rod button axis 433. The hook rod button 432 is a U-shaped button positioned around the outer edge of the lid handle 46 and can be elastically pressed and released along the thickness direction of the lid handle 46.

[0034] The locking mechanism 42 includes a body-side locking part 421 and a rotation locking mechanism 422. The body-side locking part 421 is fixedly connected to the heating base 1; the rotation locking mechanism 422 is rotatably connected to the lid handle 46 of the lid opening / closing part 4. One end of the rotation locking mechanism 422 is connected to a hook rod 431, and the other end can be rotated to switch between engaging and disengaging with the body-side locking part 421. (Reference) Figure 3A lid locking shaft 423 is provided at the connection position between the rotating locking mechanism 422 and the hook rod 431. The upper and lower parts of the rotating locking mechanism 422 can rotate around the lid locking shaft 423, which serves as the rotation axis. Furthermore, in this embodiment, a torsion spring 44 is disposed at the lid locking shaft 423, and the direction of the torque is the same as the rotation direction around the lid locking shaft 423. When the lid opening / closing part 4 is in the first position, the torsion spring 44 is in a state of accumulating elastic potential energy; when the lid opening / closing part 4 is in the second position, the torsion spring 44 is in a state of releasing elastic potential energy.

[0035] The process of switching the lid handle 46 of the lid opening and closing part 4, together with the lid 3, relative to the pot body 2 in this embodiment, to the first position and the second position is as follows: refer to Figure 1 When the lid opening / closing part 4 is in the first position, the hook rod 431 and the lid handle 46 are flush with the upper surface away from the pot body 2. Firstly, when the user presses down on the hook rod button 432 of the hook rod 431, refer to... Figure 4 With the lid handle 46 stationary, and using the hook lever button shaft 433 as the rotation axis, the hook lever 431 near the hook lever button 432 is depressed, while the hook lever 431 near the hinge shaft 41 is raised. Then, refer to... Figure 3 With the lid locking shaft 423 as the rotation axis, the raised hook 431 rotates the upper part of the rotating locking mechanism 422 away from the pot body 2, while the lower part of the rotating locking mechanism 422 rotates towards the pot body 2. Finally, when the user presses the hook button 432 down to a certain stroke, the lower end of the rotating locking mechanism 422 and the upper end of the locking part 421 on the side of the machine body switch from the original engaged state to the disengaged state. At this time, the elastic potential energy accumulated by the torsion spring 44 when the lid opening and closing part 4 is in the first position begins to be released. With the hinge shaft 41 as the rotation axis, the upper torsion bar 441 of the torsion spring 44 pulls the lid opening and closing part 4 and the lid 3 upward to the second position.

[0036] In this embodiment, to ensure that the torsion spring 44 can smoothly pull the lid opening and closing part 4 and the lid 3 upwards, the torsion spring 44 accumulates a large torque when the lid opening and closing part 4 is in the first position. However, the large torque may cause the lid opening and closing part 4 and the lid 3 to vibrate or even tip over due to excessive flipping speed during the process of switching from the first position to the second position. Therefore, in this embodiment, the cooking appliance 100 is also provided with a damping structure, which is connected to the torsion spring 44, as shown in the reference. Figure 3The damping mechanism 6 is located between the torsion spring 44 and the pot body 2. During the stroke of the pot lid handle 46 rotating from the first position to the second position, it applies damping to the torsion spring 44 to slow down the rebound speed of the torsion spring 44, thereby reducing the rotation speed of the pot lid opening and closing part 4 and the pot lid 3 when switching from the first position to the second position, and avoiding the pot lid opening and closing part 4, or even the entire cooking utensil 100, from shaking or tipping over due to excessive rotation.

[0037] When it is necessary to switch the lid 3 from the second position (separated from the pot body 2) to the first position (pressed against the top of the pot body 2), the user needs to press the lid handle 46 towards the pot body 2. This pressing action directly acts on the torsion spring 44, causing the torsion spring 44 to deform again and accumulate elastic potential energy; at the same time, the torsion bar 441 below the torsion spring 44 will generate a transmission action, pulling the lower part of the rotating locking mechanism 422 towards the locking part 421 on the body side. As the lower part of the rotating locking mechanism 422 continues to rotate, its lower end will gradually approach the upper end of the locking part 421 on the body side until the two are precisely aligned and locked together again. At this point, a stable lock is achieved between the rotating locking mechanism 422 and the locking part 421 on the body side, and the lid opening and closing part 4 drives the lid 3 to switch from the second position to the first position. The lid 3 and the pot body 2 return to a tightly pressed, sealed state, ready for subsequent cooking.

[0038] In this embodiment, since the locking mechanism 42 and the hinge shaft 41 are located on the same side of the pot body 2, the lid handle 46 does not need to span the entire top of the pot body 2 to achieve the locking mechanism 42's locking of the lid 3 and the pot body 2. To further reduce the use of plastic parts in the cooking appliance 100, refer to... Figure 5 The length of the lid handle 46 is greater than the radius of the lid 3 and less than the diameter of the lid 3, which enables the lid opening and closing part 4 to achieve a miniaturized design.

[0039] During the heating process of food and water inside the pot body 2 by the cooking appliance 100, a large amount of water vapor is generated inside the pot body 2, causing a certain amount of steam pressure to accumulate in the sealed space formed by the pot body 2 and the lid 3. If there is no effective restraint, this pressure may push the lid 3 open, causing a large amount of water vapor to escape from the pot and the temperature to drop rapidly, directly affecting the uniformity of cooking and the taste and flavor of the food, thus ruining the cooking quality. At the same time, considering that the pot body 2 and the lid 3 are made of metal as a single piece, if there is a deviation in the manufacturing process precision, it may lead to insufficient flatness of the surface of the first bending section 21A at the top of the pot body 2 and the third bending section 32 at the edge of the lid 3. Insufficient flatness will result in a large gap when the third bending section 32 of the lid 3 and the first bending section 21A at the top of the pot body 2 are fitted together. Even if the condensed water flows back to the annular water seal groove 21, the water film formed will be difficult to fill the gap and achieve the target sealing performance. Therefore, in this embodiment, the lid opening and closing part 4 also includes a pressing head 45 and an elastic element. The pressing head 45 presses against the surface of the lid 3 away from the pot body 2; one end of the elastic element is connected to the pressing head 45, and the other end is connected to the lid handle 46. Through the buffering and elasticity compensation of the elastic element, the lid 3 can be effectively prevented from deforming due to uneven pressing force when the lid handle 46 presses the lid 3 directly through the pressing head 45, or from failing to fit tightly due to insufficient pressing force, thus compensating for processing errors in flatness.

[0040] To further enhance the sealing effect and ensure that the water film between the first bent section 21A of the pot body 2 and the third bent section 32 of the pot lid 3 can fully fill the tiny gaps, the pressure head 45 and elastic element on the pot lid handle 46 are configured in multiple sets. By having multiple pressure heads 45 press against different positions in the circumferential direction of the pot lid 3, the pressing pressure applied by the pot lid opening and closing part 4 to the surface of the pot lid 3 is distributed as evenly as possible, thereby allowing the pot lid 3 to fit tightly against the pot body 2 in all directions, ensuring that the sealing performance of the water film is stable and meets the standards.

[0041] During the use of the cooking appliance 100, food may not only come into direct contact with the pot body 2, but may also adhere to the inner surface of the lid 3. Therefore, it may be necessary to clean the pot body 2 and the lid 3. In this embodiment, the top edge of the pot body 2 is provided with symmetrically distributed handles 22 at both ends, and the heating base 1 is provided with grooves 111 corresponding to the handles 22, and the two grooves 111 are symmetrically distributed about the length direction of the lid handle 46. When the pot body 2 is placed in the heating base 1, simply place the handles 22 at both ends of the pot body 2 into the grooves 111 to quickly and accurately position the pot body 2, avoiding the impact of misalignment on the subsequent sealing and heating effect. After cooking, once the lid opening and closing part 4 rotates the lid 3 from the first position to the second position, the user can directly grab the handles 22 at both ends of the pot body 2 and lift the pot body 2 out of the heating base 1 for easy cleaning of the inside of the pot body 2.

[0042] In addition, to allow for separate disassembly and cleaning of the pot lid 3, in this embodiment, the pot lid 3 can be detached from the connection point with the pot lid handle 46 of the pot lid opening and closing part 4. (See reference) Figure 2 and Figure 6 The cooking utensil 100 also includes a lid mounting part 5, which is fixedly connected to the lid 3. To ensure that the lid opening and closing part 4 in the first position can apply uniform pressing pressure to the lid 3, the lid mounting part 5 is fixed at the center of the lid 3.

[0043] In this embodiment, the lid mounting part 5 is mounted on the lid opening and closing part 4 in a manner where its position is constrained along the radial plane and its position is adjustable along the axial direction. More specifically, the lid handle 46 has a slot 52 on the side facing the pot body 2 for mating and connecting with the lid mounting part 5. To enable the lid mounting part 5 to smoothly engage or disengage from the lid handle 46, the lid opening and closing part 4 also includes a lid disengagement button 51, which is located at the end of the lid handle 46 away from the hinge axis 41, and is used to release the engagement or disengagement between the lid mounting part 5 and the lid handle 46. The engagement or disengagement process between the lid mounting part 5 and the lid handle 46 is as follows: First, the user presses down on the hook button 432 of the hook lever 431, causing the lid opening / closing part 4, along with the lid 3, to switch from the first position to the second position. Then, the user presses the lid removal button 51 with one hand while holding the lid 3 body with the other. When the lid removal button 51 is pressed to the bottom of its travel, the user can easily remove the lid 3 along with the lid mounting part 5 from the slot 52 in the lid handle 46 that matches the lid mounting part 5. After cleaning the lid 3, the user can press the lid removal button 51 again with one hand. When the lid removal button 51 is pressed to the bottom of its travel, the user holds the lid 3 with the other hand and inserts the lid mounting part 3 back into the slot 52 in the lid handle 46. Once fully inserted, the user releases the lid removal button 51, thus completing the installation of the lid mounting part 5 and the lid 3 on the lid handle 46.

[0044] In this embodiment, the pot body 2 is made of a single piece of metal, therefore, the handles 22 symmetrically arranged on both sides of the top of the pot body 2 are also made of metal. To prevent the handles 22 from becoming too hot to grip when the user needs to remove the pot body 2 from the heating base 1 after cooking, an air duct 12 is formed between the side wall of the pot body 2 and the heating base 1, and the air duct 12 passes through the handles 22. A fan 13 is provided inside the heating base 1, and the fan 13 supplies air to the air duct 12. (Reference) Figure 7As shown in Figure 8, the fan 13 is located on one side of the bottom of the heating base 1, and can introduce outside air into the air duct 12 through the bottom or side of the housing 11 of the heating base 1. When the heating base 1 of the cooking appliance 100 stops heating the pot body 2, the fan 13 can draw outside room temperature air into the air duct 12. The airflow is first guided along the air duct 12 to the bottom of the pot body 2 inside the heating base 1, initially removing the heat accumulated at the bottom of the pot body 2. Subsequently, the airflow continues to flow upward along the gap between the outer wall of the pot body 2 and the inner wall of the heating base 1. During this process, the airflow fully contacts the outer wall of the pot body 2, efficiently absorbing the heat on the surface of the pot body 2, while flowing through and removing the heat from the handle 22. Finally, the airflow that has absorbed the heat is discharged to the outside of the cooking appliance 100 through the groove 111 provided on the top of the housing of the heating base 1, realizing the cooling of the handle 22 and the pot body 2, allowing the user to safely remove and put away the pot body 2 after cooking, improving the safety and convenience of using the cooking appliance 100.

[0045] In this embodiment, the airflow introduced into the heating base 1 by the fan 13 and the air duct 12, in addition to having the function of the handle 22 for cooling the pot body 2 as described above, can also promote the uniform distribution of heat on the surface of the pot body 2 when the heating base 1 heats the pot body 2, thereby further improving the cooking effect.

[0046] refer to Figure 7 An electromagnetic heating coil 14 is installed at the bottom of the heating base 1. When the electromagnetic heating coil 14 is activated, it will preferentially heat the bottom of the pot body 2. This heating method can easily cause heat to concentrate at the bottom of the pot body 2, which may cause the food to burn due to excessively high local temperature at the contact point with the bottom of the pot body 2, or cause uneven cooking of the food inside the pot body 2 due to excessive temperature difference between the top and bottom, thus affecting the cooking quality. Therefore, in this embodiment, during the operation of the cooking appliance 100, a continuous airflow can be introduced into the gap between the outer wall of the pot body 2 and the inner wall of the heating base 1 using the fan 13 and the air duct 12. This will disperse the concentrated heat transferred to the bottom of the pot body 2 by the electromagnetic heating coil 14 upward along the outer wall of the pot body 2 to the entire surface of the pot body 2, making the temperature of each area of ​​the pot body 2 more uniform and further optimizing the user's cooking experience.

[0047] During the use of the cooking appliance 100, pressure gradually accumulates within the sealed space formed by the pot body 2 and the lid 3 due to the continuous generation of steam. Excessive pressure can not only affect cooking safety but also disrupt the stable cooking environment inside the pot. Therefore, in this embodiment, the lid 3 is provided with a vent 31 at a position offset from the lid opening / closing part 4, used to expel the steam generated inside the pot body 2 to the outside at a controllable flow rate and velocity during cooking. (Reference) Figure 1 and Figure 5When the user is in the operating position near the hook button 432, the vent 31 is located on the rear side of the lid 3 away from the hook button 432. In this embodiment, there are two vents 31 on the lid, and the two vents 31 are symmetrically distributed about the length of the lid handle 46. The above design of the vent 31 position can effectively avoid the activity area of ​​the user's hands or other parts of the body during daily operation, preventing the exhaust of high-temperature water vapor from directly contacting the user, and further improving the safety of using the cooking appliance 100.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
