Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, and more particularly to cooking appliances. Background Technology
[0002] In the design and development of cooking appliances, a combination of floating and fixed heating elements is often used to improve heating efficiency and uniformity. The floating heating element can move up and down according to the weight or volume of the contents of the inner pot to adapt to different cooking needs. The floating heating element is usually connected to other parts of the cooking appliance via elastic elements such as springs to achieve its floating function. However, in actual use, people often remove the inner pot for other cooking operations. Without the support and constraint of the inner pot and its contents, the floating heating element is prone to being unloaded, affecting the safety and lifespan of the cooking appliance.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
[0041] The following is combined Figures 1 to 7 Describes the cooking appliance of this application.
[0042] According to an embodiment of this application, a cooking utensil is provided. Please refer to... Figures 1 to 3 The cooking appliance includes an outer pot 100, an inner pot 200, and a heating assembly 300. The outer pot 100 has a mounting cavity 101; the inner pot 200 is movably mounted in the mounting cavity 101; the heating assembly 300 is disposed between the outer pot 100 and the inner pot 200, and the heating assembly 300 includes a fixed heating element 310, a floating heating element 320, and a first elastic element 330; the floating heating element 320 is buoyant relative to the fixed heating element 310 via the first elastic element 330, and the first elastic element 330 provides elasticity for the floating heating element 320 to move towards the inner pot 200. The fixed heating element 310 and the floating heating element 320 are both used to heat the inner pot 200. The fixed heating element 310 is provided with a first limiting structure 312, and the floating heating element 320 is provided with a second limiting structure 322. The first limiting structure 312 is located on the side of the second limiting structure 322 close to the inner pot 200. When the inner pot 200 is disassembled from the mounting cavity 101, the floating heating element 320 is in a floating state. The first limiting structure 312 is used to limit the maximum floating displacement of the second limiting structure 322 under the action of the first elastic element 330.
[0043] According to the embodiments of this application, the cooking appliance has a first limiting structure 312 on the fixed heating element 310 and a second limiting structure 322 on the floating heating element 320. This ensures that the movement range of the floating heating element 320 is effectively controlled, preventing excessive floating of the floating heating element 320 when the inner pot 200 is not placed inside, thus avoiding potential safety hazards. This design effectively eliminates potential safety hazards that the floating heating element 320 may cause to other components of the cooking appliance, such as electrical short circuits, localized overheating, mechanical damage, or the risk of users coming into contact with high-temperature parts. At the same time, the stable operation of the floating heating element 320 also ensures heating uniformity, improving cooking results and equipment reliability.
[0044] Therefore, the design of the first limiting structure 312 and the second limiting structure 322 in this embodiment not only restricts the movement range of the floating heating element 320, but also indirectly ensures the contact stability between the floating heating element 320 and the fixed heating element 310. This ensures that the temperature measuring element can accurately detect the temperature when the inner pot 200 is not placed, avoiding safety hazards caused by temperature detection failure. At the same time, this design further improves the overall safety and reliability of the cooking appliance.
[0045] Understandably, the outer pot 100 is the outer structure of the cooking utensil, and it has a mounting cavity 101 to accommodate the inner pot 200 and the heating element 300. The outer pot 100 can be made of a high-temperature resistant and corrosion-resistant metal. The inner pot 200 is movably fitted into the mounting cavity 101 of the outer pot 100, facilitating the user's loading and unloading of food. The inner pot 200 can also be made of a high-temperature resistant and corrosion-resistant metal, and its surface may have a non-stick coating to reduce friction between food and the inner pot 200, making it easier to clean.
[0046] A heating assembly 300 is disposed between the outer pot 100 and the inner pot 200, responsible for providing the heat required for cooking. The heating assembly 300 includes a fixed heating element 310, a floating heating element 320, and a first elastic element 330. Exemplarily, the fixed heating element 310 is fixedly connected to the outer pot 100, providing a stable heat source. The floating heating element 320 is floatingly connected to the outer pot 100 via the first elastic element 330, and can float up and down according to the weight or volume of the contents in the inner pot 200. The first elastic element 330 serves as an elastic element connecting the floating heating element 320 and the outer pot 100. The first elastic element 330 can be a spring or elastic sheet, possessing characteristics such as good elasticity and high-temperature resistance. Through the elastic action of the first elastic element 330, the floating heating element 320 can flexibly float up and down, adapting to the cooking needs of different ingredients.
[0047] In one embodiment, to prevent the floating heating element 320 from floating excessively when the inner pot 200 is disassembled, a first limiting structure 312 is provided on the fixed heating element 310, and a second limiting structure 322 is provided on the floating heating element 320. The first limiting structure 312 is located in the moving direction of the second limiting structure 322 and is positioned above the second limiting structure 322. When the inner pot 200 is disassembled, the floating heating element 320 is in a floating state, but due to the cooperative action of the first limiting structure 312 and the second limiting structure 322, the upward floating range of the floating heating element 320 is effectively controlled, avoiding safety hazards and equipment damage.
[0048] Specifically, the fixed heating element 310 and the floating heating element 320 can be two parts obtained by splitting the heating plate. Generally, the heating plate is disc-shaped, and the fixed and floating heating elements can be distinguished by an inner-outer arrangement, meaning one of the fixed and floating heating elements surrounds the other. Alternatively, the fixed and floating heating elements can be distinguished by a fan-shaped arrangement, where two radii dividing the heating plate at its center ultimately form two heating zones, used as the fixed and floating heating elements respectively.
[0049] The first limiting structure 312 is disposed on the fixed heating element 310 to limit the movement range of the floating heating element 320. The first limiting structure 312 can be in the form of a protrusion, boss, or slot, and can reliably abut against the second limiting structure 322. The second limiting structure 322 is disposed on the floating heating element 320. When the floating heating element 320 floats to a certain position, it abuts against the first limiting structure 312, thereby stopping its movement. The second limiting structure 322 can also be in the form of a protrusion, boss, or slot, and matches the first limiting structure 312.
[0050] Before the inner pot 200 is placed into the receiving cavity and before the floating heating element 320 is pressed down, the first limiting structure 312 and the second limiting structure 322 can maintain the contact relationship between the floating heating element 320 and the fixed heating element 310, so that heat can be transferred between the fixed heating element 310 and the floating heating element 320 before the inner pot 200 is placed in, which can limit the temperature of the floating heating element 320 from being too high.
[0051] According to one embodiment of this application, the fixed heating element 310 is fixedly connected to the outer pot 100, and the first elastic element 330 is connected between the floating heating element 320 and the outer pot 100.
[0052] The fixed heating element 310 is fixedly connected to the outer pot 100, providing a stable heat source. The floating heating element 320 is floatingly connected to the outer pot 100 via a first elastic element 330, and can float up and down according to the weight or volume of the contents in the inner pot 200. The first elastic element 330 serves as an elastic element connecting the floating heating element 320 and the outer pot 100. The first elastic element 330 can be a spring or elastic sheet, etc., and has the characteristics of good elasticity and high temperature resistance. Through the elastic action of the first elastic element 330, the floating heating element 320 can flexibly float up and down to adapt to the cooking needs of different ingredients.
[0053] According to one embodiment of this application, the fixed heating element 310 is provided with a first heating surface 311, and the floating heating element 320 is provided with a second heating surface 321. When the inner pot 200 is assembled into the mounting cavity 101 by its own weight, the floating heating element 320 is in a first position. In the first position, the second limiting structure 322 moves away from the first limiting structure 312, and both the first heating surface 311 and the second heating surface 321 abut against the inner pot 200.
[0054] The first heating surface 311 is always stably mounted on the fixed heating element 310, providing a stable heat source for the inner pot 200. The second heating surface 321 can float up and down according to the weight or volume of the contents in the inner pot 200. In the first position, both the first heating surface 311 and the second heating surface 321 are in contact with the inner pot 200. Both the fixed heating element 310 and the floating heating element 320 heat the inner pot 200, and the heat can be efficiently transferred to the food in the inner pot 200, improving cooking efficiency and the taste of the food.
[0055] According to one embodiment of this application, please refer to Figure 4 When the inner pot 200 is removed from the mounting cavity 101, the floating heating element 320 is in the second position, and in the second position, the second limiting structure 322 abuts against the first limiting structure 312.
[0056] When the inner pot 200 is removed and leaves the mounting cavity 101, the floating heating element 320 will begin to float upwards due to the loss of the gravity support of the inner pot 200, entering the second position. In the second position, the second limiting structure 322 will abut against the first limiting structure 312, thereby limiting the further upward movement of the floating heating element 320.
[0057] Moreover, in some embodiments, such as Figure 3 As shown, in the second position, the second heating surface 321 is higher than the first heating surface 311.
[0058] According to one embodiment of this application, the first limiting structure 312 extends outward relative to the fixed heating element 310, and the second limiting structure 322 extends outward relative to the floating heating element 320.
[0059] The first limiting structure 312 extends outward relative to the fixed heating element 310, forming a spatial "lug" structure. The second limiting structure 322 extends outward relative to the floating heating element 320, also forming a spatial "lug" structure. The first limiting structure 312 and the second limiting structure 322 are adapted to be staggered in the moving direction of the floating heating element 320.
[0060] According to one embodiment of this application, the first limiting structure 312 extends outward relative to the fixed heating element 310, and the second limiting structure 322 extends outward relative to the floating heating element 320. The first limiting structure 312 is provided with a first chamfer 313 at a position for abutting against the second limiting structure 322, and the second limiting structure 322 is adapted to abut against the first chamfer 313.
[0061] Specifically, the lower side of the fixed heating element 310 is provided with a first chamfer 313, and the second limiting structure 322 can accurately abut against the first chamfer 313 of the first limiting structure 312, so that heat can be transferred to the fixed heating element 310 and the thermostat to prevent the risk from expanding.
[0062] According to one embodiment of this application, a second chamfer 325 is provided on the second limiting structure 322 at the position for abutting against the first limiting structure 312. The second chamfer 325 is provided corresponding to the first chamfer 313, which ensures the stability and safety between the second limiting structure 322 and the first limiting structure 312.
[0063] In one embodiment, a chamfer of approximately 45° is provided on the lower side of the outer circle of the fixed heating element 310, forming a downward-facing slope on the lower surface of the outer diameter of the fixed heating element 310. A chamfer of approximately 45° is also provided on the upper side of the inner circle of the floating heating element 320, forming an upward-facing slope on the upper surface of the inner diameter of the floating heating element 320, opposite to the lower surface of the outer diameter of the fixed heating element 310. This ensures that the outer diameter of the working surface of the fixed heating element 310 is smaller than the inner diameter of the working surface of the floating heating element 320.
[0064] Meanwhile, the chamfer size of the inner diameter of the floating heating element 320 should be smaller than the chamfer size of the outer diameter of the fixed heating element 310, so that when the floating heating element 320 is at its lowest position, its working surface can be lower than the working surface of the fixed heating element 310. This ensures that when the floating heating element 320 is pressed down, the inner pot 200 can contact the floating heating element 320 and the fixed heating element 310 at the same time.
[0065] According to one embodiment of this application, please refer to Figure 5The first limiting structure 312 has a first contact portion 315, and the second limiting structure 322 has a second contact portion 323. The first contact portion 315 is located above the first chamfer 313, and the second contact portion 323 is located above the second chamfer 325. The first contact portion 315 has a first contact surface 316, and the second contact portion 323 has a second contact surface 324. Both the first contact surface 316 and the second contact surface 324 are parallel to the moving direction of the floating heating element 320. In other words, in such a case... Figure 5 At the angle shown, both the first contact surface 316 and the second contact surface 324 are arranged longitudinally. When the second chamfer 325 abuts against the first chamfer 313, the second contact surface 324 abuts against the first contact surface 316.
[0066] If there are foreign objects such as rice grains between the floating heating element 320 and the fixed heating element 310, a certain gap can be formed between the opposing surfaces of the floating heating element 320 and the fixed heating element 310 when the floating heating element 320 is pressed down (such as when the inner pot 200 is placed into the mounting cavity 101). This gap can guide the rice grains or similar foreign objects to fall to the bottom of the outer pot 100, thereby preventing them from getting stuck in the gap between the floating heating element 320 and the fixed heating element 310. This design not only prevents foreign objects from obstructing the floating of the heating plate, but also ensures close contact between the floating heating element 320 and the fixed heating element 310 and the inner pot 200, guaranteeing the heat transfer effect.
[0067] When the floating heating element 320 reaches the second position, the first contact portion 315 and the second contact portion 323 come into contact to form a structure that prevents rice grains from entering, thus preventing rice grains or similar foreign objects from entering the gap between the floating heating element 320 and the fixed heating element 310.
[0068] Even if there are a few foreign objects (such as rice grains) between the floating heating element 320 and the fixed heating element 310 before using the cooking appliance, the user can safely place the inner pot 200 into the mounting cavity 101. During the downward pressing process, the floating heating element 320 will guide the foreign objects to the bottom of the outer pot 100 through the gap, ensuring the smooth progress of the cooking process.
[0069] After cooking, the user can remove the inner pot 200 for cleaning. At this time, the floating heating element 320 will automatically float to the second position. If any foreign objects fall into the bottom of the outer pot 100 during use, the user can flip the pot over to pour them out, which will have minimal impact on use.
[0070] According to one embodiment of this application, please refer to Figure 6 and Figure 7The first limiting structure 312 extends outward relative to the fixed heating element 310, and the second limiting structure 322 extends outward relative to the floating heating element 320. The first limiting structure 312 has a first stepped surface 314 at a position for abutting against the second limiting structure 322, and the second limiting structure 322 has a second stepped surface 326 at a position for abutting against the first limiting structure 312. The second stepped surface 326 is adapted to abut against the first stepped surface 314.
[0071] The first stepped surface 314 is provided on the first limiting structure 312, forming an effective contact surface with the second stepped surface 326, thereby enhancing the stability and reliability of the limiting structure. The second stepped surface 326 is provided on the second limiting structure 322, corresponding to the first stepped surface 314. The design of the second stepped surface 326 should ensure that after the failure of the first elastic element 330, the second stepped surface 326 can smoothly abut against the first stepped surface 314, thereby forming a stable limiting relationship.
[0072] According to one embodiment of this application, the first limiting structure 312 and the fixed heating element 310 are integrally formed. In this embodiment, the fixed heating element 310 and the first limiting structure 312 are processed by integral molding technology, ensuring a tight connection and overall strength between the two.
[0073] According to one embodiment of this application, the second limiting structure 322 and the floating heating element 320 are integrally formed. In this embodiment, the floating heating element 320 and the second limiting structure 322 are processed by integral forming technology, ensuring a tight bond and overall strength between the two.
[0074] According to one embodiment of this application, a fixed heating element 310 and a floating heating element 320 are disposed at the bottom of the mounting cavity 101, with the floating heating element 320 surrounding the fixed heating element 310. In this embodiment, the fixed heating element 310 is located at the center, while the floating heating element 320 is distributed around the periphery of the fixed heating element 310. Since the floating heating element 320 can cover a wider heating area, this design helps to improve heating efficiency and make the heat more evenly distributed on the bottom of the cooking appliance.
[0075] According to one embodiment of this application, a fixed heating element 310 and a floating heating element 320 are disposed at the bottom of the mounting cavity 101, with the fixed heating element 310 surrounding the floating heating element 320. In this embodiment, the floating heating element 320 is located at the center, while the fixed heating element 310 is distributed around the periphery of the floating heating element 320.
[0076] According to one embodiment of this application, the heating assembly 300 includes a thermostat and a second elastic element. The thermostat is floatingly connected to the outer pot 100 through the second elastic element. In a first position, the first heating surface 311, the second heating surface 321, and the thermostat all abut against the inner pot 200.
[0077] The thermostat monitors temperature changes during the heating process of the inner pot 200 and cuts off the power when the preset temperature is reached to prevent safety hazards caused by overheating. In this embodiment, the thermostat is floatingly connected to the outer pot 100 via a second elastic element. The thermostat maintains a certain degree of floating during the assembly of the inner pot 200 into the receiving cavity, thereby better conforming to the inner pot 200 and ensuring measurement accuracy. The second elastic element provides necessary support and also allows the thermostat some displacement space during heating, further improving the stability and reliability of the measurement.
[0078] In the first position, when the inner pot 200 is assembled in the mounting cavity 101, the first heating surface 311 and the second heating surface 321 of the floating heating element 320 are both in close contact with the bottom and side wall (or designated heating area) of the inner pot 200. Simultaneously, the thermostat is also in contact with the inner pot 200 via the action of the second elastic element. The thermostat can accurately monitor the temperature changes of the inner pot 200 and promptly cut off the power to prevent overheating.
[0079] In one embodiment, the thermostat, the fixed heating element 310, and the floating heating element 320 are all located at the bottom of the mounting cavity 101. The fixed heating element 310 is arranged around the thermostat, and the floating heating element 320 is arranged around the fixed heating element 310.
[0080] In this embodiment, the thermostat can be used to detect the temperature of the fixed heating element 310, which serves as a limiting device for the upper limit of the floating position of the floating heating element 320. When the floating heating element 320 moves upward to contact the fixed heating element 310, a new heat transfer path is created, transferring the heat from the floating heating element 320 to the fixed heating element 310 and the thermostat, controlling the heating process and preventing greater danger.
[0081] According to one embodiment of this application, the cooking appliance further includes a thermostat 400, which is in contact with the fixed heating element 310 and is used to detect the temperature of the fixed heating element 310.
[0082] The function of the thermostat 400 is to ensure that the heating process is within a safe and controllable range by monitoring the temperature change of the fixed heating element 310 in real time. When the temperature of the fixed heating element 310 exceeds the preset threshold, the thermostat 400 will trigger a protection mechanism, such as cutting off the power or reducing the heating power, thereby avoiding safety hazards caused by overheating, such as equipment damage, fire risk, or user burns.
[0083] Furthermore, the design of the thermostat 400 further enhances the intelligent functions of the cooking appliance. Through precise temperature detection and control, the thermostat 400 optimizes heating efficiency, ensures even heating of food, and improves cooking results. Simultaneously, the direct contact design between the thermostat 400 and the fixed heating element 310 allows for rapid response to temperature changes, improving the accuracy and real-time nature of temperature detection, and providing greater safety and reliability for the cooking process.
[0084] According to one embodiment of this application, the cooking appliance further includes a thermostat 400, wherein the fixed heating element 310 provides heat to the inner pot 200 by abutting against the inner pot 200, the temperature sensing part of the thermostat 400 is spaced apart from the fixed heating element 310, the thermostat 400 is used to detect the temperature of the inner pot 200, and the floating heating element 320 is spaced apart from the inner pot 200 when the second limiting part abuts against the first limiting part.
[0085] The temperature sensing part of the thermostat 400 is spaced apart from the fixed heating element 310. This design allows the thermostat 400 to directly detect the temperature of the inner pot 200, rather than the temperature of the fixed heating element 310, thus more accurately reflecting the actual temperature of the inner pot 200 and achieving precise control over the cooking process. When the second limiting part abuts against the first limiting part, the floating heating element 320 maintains a spaced arrangement with the inner pot 200. This design ensures that the floating heating element 320 does not directly contact the inner pot 200, avoiding uneven heating or safety hazards caused by excessive floating or misalignment of the floating heating element 320.
[0086] The thermostat 400 can monitor the cooking status in real time by detecting the temperature of the inner pot 200. When the temperature of the inner pot 200 is too high, the thermostat 400 can trigger a protection mechanism (such as cutting off the power or reducing the heating power) to prevent safety hazards caused by overheating, such as food burning, equipment damage, or fire risk.
[0087] When the second limiting part abuts against the first limiting part, the floating heating element 320 and the inner pot 200 are arranged at intervals to avoid the problem of local overheating that may be caused when the floating heating element 320 directly heats the inner pot 200.
[0088] According to one embodiment of this application, there are multiple first elastic elements 330, which are evenly distributed between the floating heating element 320 and the outer pot 100.
[0089] In this embodiment, multiple first elastic elements 330 are used to support and buffer the floating heating element 320. These elastic elements are evenly distributed between the floating heating element 320 and the outer pot 100 to ensure that the floating heating element 320 can float smoothly and be subjected to uniform force in all directions.
[0090] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should be covered within the scope of the claims of this application.
