Description
Technical Field
[0001] The present application belongs to the technical field of kitchen appliances, and in particular relates to a cooking appliance with zoned heating. Background Art
[0002] As the pace of life accelerates, people have higher and higher requirements for cooking efficiency. Some users expect to use one cooking utensil to cook different ingredients at the same time. Traditional cooking utensils set up multiple independent cooking cavities and use heating devices to heat the multiple cooking cavities to meet the needs of users to cook multiple ingredients at the same time.
[0003] However, due to the different types of ingredients and cooking methods, the heating time required for the ingredients in each cooking cavity is different. The heating device in the traditional cooking cavity can only heat each cooking cavity at the same time, but cannot heat each cooking cavity separately. When the ingredients in each cooking cavity are cooked, some easy-to-cook ingredients may be overcooked, affecting the taste of the ingredients. In addition, the traditional heating device is limited by the arrangement position of the heating tube, which easily leads to high temperature in the center of the heating device and low temperature in the periphery, resulting in uneven heat supply to the cooking cavity and deformation of the heating device due to temperature difference. In particular, in cooking utensils with a pot body and a base separately arranged, since the heating device is arranged on the base, when the heating device is deformed, especially when the central area of the heating device is deformed, when the pot body is placed on the base, the fit between the heating device and the pot body is reduced, and the central area of the heating device is a relatively large area in contact with the pot body. This deformation will cause the heat transfer from the heating device to the pot body to be reduced, thereby affecting the cooking thermal efficiency and user experience. Utility Model Content
[0004] The present application provides a zoned heating cooking utensil to solve the technical problem that the central area of the heating device on the base of the traditional cooking utensil with the base and the pot body separately arranged is easy to deform, resulting in reduced heat transfer efficiency between the heating device and the pot body.
[0005] The technical solution adopted in this application is:
[0006] A zoned heating cooking utensil comprises a separately arranged pot body and a base, wherein the base is provided with a heating device, wherein the pot body is divided into a plurality of independent cooking cavities by partitions, wherein the heating device comprises heating zones corresponding to the cooking cavities one by one, wherein each heating zone is provided with a heating tube, wherein the heating tube comprises a heating section and a cold end section connected to the heating section, wherein the cold end section is arranged in a central area of the heating zone.
[0007] The cooking appliance described in this application also includes the following additional technical features:
[0008] Each heating zone is provided with a plurality of heating tubes, the cold end sections of the heating tubes belonging to the same heating zone are dispersedly arranged in the central area of the heating zone, and the heating sections of the heating tubes belonging to the same heating zone are extended to the periphery of the heating zone.
[0009] Each of the heating tubes comprises a connection end for being connected in parallel with each other, and the connection end is arranged near the central area of the heating zone.
[0010] The heating device comprises a plurality of heating plates corresponding to the cooking cavities one by one, and a heating zone is formed on each heating plate.
[0011] One of the heating plates is arranged to float relative to the other heating plate to fit the bottom of the pot body.
[0012] The pot body has two cooking cavities, and the heating device comprises a left heating plate and a right heating plate distributed on the left and right.
[0013] The heating device comprises a heating plate, and a plurality of heating zones are formed on the heating plate.
[0014] The heating plate is provided with two heating zones along the left-right direction, and the heating tubes on the two heating zones are arranged symmetrically.
[0015] The cold end sections of the heating tubes on the two heating zones are located on the inner sides of the two heating zones facing each other.
[0016] The heating plate and the heating tube are integrally cast, and a material injection port surrounded by a plurality of heating partitions is provided in the center of the heating plate.
[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:
[0018] 1. The present application provides a zoned heating cooking device, comprising a plurality of independent cooking cavities, and a heating device is provided with heating zones corresponding to the plurality of cooking cavities one by one, so that each heating zone can independently heat the cooking cavity corresponding to it. When a user uses the cooking device to cook a variety of different ingredients, the ingredients can be placed in the cooking cavities respectively for simultaneous cooking. After the ingredients in a certain cooking cavity are cooked, the user can choose to stop heating the heating zone corresponding to it, so as to avoid overheating of the ingredients in the cooking zone, thereby maintaining the taste of the ingredients. That is, the present application provides a plurality of cooking cavities and a plurality of heating zones corresponding to the cooking cavities one by one, so that the cooking device can be used to cook a variety of different ingredients at the same time, thereby greatly saving the cooking time of the user, and the plurality of cooking cavities can be independently heated, thereby satisfying the separate cooking of ingredients with different heating times, so that the ingredients in each cooking cavity can achieve a better cooking taste by controlling different heating times, thereby greatly improving the user's experience.
[0019] Since the heating tube of the present application includes a heating section and a cold end section connected to the heating section, and the cold end section is arranged in the central area of the heating zone, the heat convergence in the central area of the heating zone is reduced to a certain extent, which helps to improve the uniformity of heat distribution in the peripheral area of the heating zone. On the one hand, each heating zone can achieve uniform heating of the corresponding cooking cavity, improve the uniformity of heating of the food, help to improve the cooking taste of the food, and enhance the user experience; on the other hand, since the heat of each heating zone is evenly distributed, the possibility of a large temperature difference between the central area and the peripheral area caused by the convergence of heat in the central area is reduced, thereby reducing the probability of local deformation of the heating zone caused by long-term temperature difference, especially the deformation of the central area of the heating zone, which not only helps to improve the service life of the heating device, but also ensures that when the pot body is placed on the base, the heating zone can maintain a large area of contact with the pot body, thereby ensuring the heat transfer efficiency of the heating device to the pot body, and then ensuring the cooking thermal efficiency.
[0020] 2. As a preferred embodiment of the present application, by providing a plurality of heating tubes, the uniformity of heat distribution in each heating zone can be improved, thereby further improving the uniformity of heat transfer to the cooking cavity, so as to improve the uniformity of heating the food in the cooking cavity; and the cold end sections of each heating tube are arranged in a dispersed manner in the central area of the heating zone, which, on the one hand, further reduces the large amount of heat accumulation in the central area, helps to improve the uniformity of heat distribution in the heating zone and reduce the possibility of temperature difference in the heating zone, thereby greatly reducing the probability of deformation of the central area of the heating zone, ensuring the effective fit between the central area of the heating zone and the pot body, and ensuring the heat transfer efficiency; on the other hand, since the cold end sections usually need to be connected to pipelines, circuits, etc., dispersing the cold end sections helps to avoid mutual interference among the cold end sections, helps to improve the routing layout of pipelines, circuits, etc. connected to the cold end sections, and optimizes the structural design of the heating zones.
[0021] 3. As a preferred embodiment of the present application, each of the heating tubes includes a connection end for parallel connection, and the connection end is arranged near the central area of the heating zone. With such arrangement, each heating zone has the function of controlling each heating tube individually, and the user can control the working number of the heating tubes in each heating zone by selecting such as cooking power, heating temperature, etc., so as to realize the function of adjusting the heating power and temperature of the heating zone, thereby satisfying the adjustment of the cooking temperature in each cooking cavity, facilitating the user to adjust the cooking cavity temperature according to different ingredients and different cooking methods, and improving the user's experience; in addition, since the temperature of the central area of each heating zone is lower than the temperature of the rest of the heating zone, arranging the connection end near the central area of the heating zone helps to reduce the possibility of high heat affecting the connection end, and provides a guarantee for the stable operation of the connection end.
[0022] 4. As a preferred embodiment of the present application, since a heating zone is formed on each heating plate, when the food in a cooking cavity is cooked and the corresponding heating zone needs to be stopped for further heating, it is ensured that the heating zone will not continue to transfer heat to the cooking cavity due to the heat conduction of the other adjacent heating zones, thereby improving the independence of the heating zones, helping to maintain the taste of the food and improving the user experience. Moreover, by providing multiple heating plates corresponding to the cooking cavities one by one, when one of the heating plates fails, the failed heating plate can be repaired or replaced separately, reducing maintenance costs.
[0023] 5. As a preferred embodiment of the present application, one of the heating plates is arranged to float relative to the other heating plate so as to fit the bottom of the pot body. During actual use, the portion of the bottom of the pot body facing the heating tube is heated at a higher temperature than the portion without the heating tube or the portion between the winding gaps of the heating tube. After long-term use, the portion of the pot body facing the heating tube is likely to be deformed, resulting in an increase in the gap between the portion and the heating plate. This embodiment arranges one of the heating plates to float relative to the other heating plate, so that when the pot body is deformed, the corresponding heating plate can continue to fit the deformed portion of the pot body by floating, so that the heat generated by the heating plate can be conducted to the pot body through direct contact with the pot body, thereby improving the heat transfer performance and thermal efficiency, making the food heated more evenly, which can not only reduce the probability of the bottom of the pot being burnt during cooking, but also improve the cooking taste of the food, thereby improving the user experience.
[0024] 6. As a preferred embodiment of the present application, the heating device includes a heating plate, and the plurality of heating zones are formed on the heating plate. With such a configuration, only one heating plate is required to provide a plurality of heating zones, and during the assembly process, only one heating plate needs to be installed to achieve the installation of the plurality of heating zones, which reduces the difficulty of assembling the heating plate and helps to improve the assembly efficiency of the cooking appliance.

[0041] The present application provides a zoned heating cooking device, comprising a plurality of independent cooking cavities 11, and a heating device is provided with heating zones 2 corresponding to the plurality of cooking cavities 11, so that each heating zone 2 can independently heat the corresponding cooking cavity 11. When a user uses the cooking device to cook a variety of different ingredients, the ingredients can be placed in the cooking cavities 11 for simultaneous cooking. After the ingredients in a certain cooking cavity 11 are cooked, the user can choose to stop heating the corresponding heating zone 2 to avoid overheating the ingredients in the cooking zone, thereby maintaining the taste of the ingredients. That is, the present application provides a plurality of cooking cavities 11 and a plurality of heating zones 2 corresponding to the cooking cavities 11, so that the cooking device can be used to cook a variety of different ingredients at the same time, which greatly saves the cooking time of the user, and can independently heat the plurality of cooking cavities 11, thereby satisfying the separate cooking of ingredients with different heating times, so that the ingredients in each cooking cavity 11 can achieve a better cooking taste by controlling different heating times, thereby greatly improving the user's experience. Since the heating tube 3 of the present application includes a heating section 31 and a cold end section 32 connected to the heating section 31, and the cold end section 32 is arranged in the central area of the heating zone 2, the heat convergence in the central area of the heating zone 2 is reduced to a certain extent, which helps to improve the uniformity of heat distribution in the peripheral area of the heating zone 2. On the one hand, each heating zone 2 can achieve uniform heating of the corresponding cooking cavity 11, improve the uniformity of heating of the food, help to improve the cooking taste of the food, and enhance the user experience; on the other hand, since the heat of each heating zone 2 is evenly distributed, the possibility of a large temperature difference between the central area and the peripheral area caused by the convergence of heat in the central area is reduced, thereby reducing the probability of local deformation of the heating zone 2 caused by long-term temperature difference, especially deformation of the central area of the heating zone 2, which not only helps to improve the service life of the heating device, but also ensures that when the pot body 1 is placed on the base, the heating zone 2 can maintain a large area of contact with the pot body 1, thereby ensuring the heat transfer efficiency of the heating device to the pot body 1, and then ensuring the cooking thermal efficiency.
[0042] Specifically, the cooking appliance further includes a temperature control unit, and the cold end section 32 is used to connect the temperature control unit, which mainly controls the operating state of the heating tube 3. The temperature control unit may be, for example, a temperature controller or a circuit board.
[0043] The present application does not limit the division range of the central area. Taking the heating partition 2 as a circle as an example, the central area refers to the part close to the center of the circle; taking the heating partition 2 as a rectangle as an example, the central area refers to the area around the centroid of the rectangle. The cold end section 32 can be at a certain distance from the centroid and also belongs to the central area referred to in the present application.
[0044] As an implementation mode of the present application, each heating zone 2 is provided with a heating tube 3 , which is arranged in a winding manner in the heating zone 2 , and the cold end section of the heating tube 3 is located in the central area of the heating zone 2 .
[0045] As a preferred implementation of the present application, Figure 2 As shown, each heating zone 2 is provided with a plurality of heating tubes 3, the cold end sections 32 of the heating tubes 3 belonging to the same heating zone 2 are dispersedly arranged in the central area of the heating zone 2, and the heating sections 31 of the heating tubes 3 belonging to the same heating zone 2 are extended to the periphery of the heating zone 2.
[0046] In the above-mentioned embodiment, the specific winding or extending form of the heating tube 3 or the extending arrangement to the periphery of the heating zone 2 is not limited, for example, it can be Figures 2 to 4 The circumferential direction of the heating zone 2 as shown in the figure may be extended sequentially, or the circumferential direction of the heating zone 2 may be extended in a circuitous manner and repeatedly bent in multiple sections along the heating zone.
[0047] By providing a plurality of heating tubes 3, the uniformity of heat distribution in the heating zone 2 can be improved, thereby further improving the uniformity of heat transfer to the cooking cavity 11, so as to improve the uniformity of heating the food in the cooking cavity 11; and the cold end sections 32 of each heating tube 3 are arranged in a dispersed manner in the central area of the heating zone 2, which, on the one hand, further reduces the large amount of heat accumulation in the central area, helps to improve the uniformity of heat distribution in the heating zone 2 and reduce the possibility of temperature difference in the heating zone 2, thereby greatly reducing the probability of deformation in the central area of the heating zone 2, ensuring the effective fit between the central area of the heating zone 2 and the pot body 1, and ensuring the heat transfer efficiency; on the other hand, since the cold end sections 32 usually need to be connected to pipelines, circuits, etc., dispersing the cold end sections 32 helps to avoid mutual interference among the cold end sections 32, helps to improve the routing of pipelines, circuits, etc. connected to the cold end sections 32, and optimizes the structural design of the heating zone 2.
[0048] As a preferred example of this embodiment, Figure 2As shown, each of the heating tubes 3 includes a connection end 33 for parallel connection, and the connection end 33 is arranged near the central area of the heating partition 2. With such arrangement, each heating partition 2 has the function of controlling each heating tube 3 individually, and the user can control the working number of the heating tubes 3 in each heating partition 2 by selecting, for example, cooking power, heating temperature, etc., so as to realize the function of adjusting the heating power and temperature of the heating partition 2, thereby satisfying the adjustment of the cooking temperature in each cooking cavity 11, facilitating the user to adjust the temperature of the cooking cavity 11 according to different ingredients and different cooking methods, and improving the user's use experience; in addition, since the temperature of the central area of each heating partition 2 is lower than the temperature of the other areas of the heating partition 2, arranging the connection end 33 near the central area of the heating partition 2 helps to reduce the possibility of high heat affecting the connection end 33, and provides a guarantee for the stable operation of the connection end 33.
[0049] The present application does not limit the formation method of the heating zone 2, and it can adopt any of the following embodiments:
[0050] Implementation method 1: Figure 3 As shown, the heating device includes a plurality of heating plates 4 corresponding to the cooking cavity 11, and a heating zone 2 is formed on each heating plate 4. Since a heating zone 2 is formed on each heating plate 4, when the food in a cooking cavity 11 is cooked and the corresponding heating zone 2 needs to be controlled to stop heating, it is ensured that the heating zone 2 will not continue to transfer heat to the cooking cavity 11 due to the heat conduction of the remaining adjacent heating zones 2, thereby improving the independence of each heating zone 2, helping to maintain the taste of the food and improving the user experience. Moreover, by providing a plurality of heating plates 4 corresponding to the cooking cavity 11, when one of the heating plates 4 fails, the failed heating plate 4 can be repaired or replaced separately, thereby reducing maintenance costs.
[0051] As a preferred embodiment of the embodiment 2, one of the heating plates 4 is arranged to float relative to the other heating plate 4 so as to fit the bottom of the pot body 1. In actual use, the portion of the bottom of the pot body 1 facing the heating tube 3 is heated at a higher temperature than the portion without the heating tube 3 or the portion between the winding gaps of the heating tube 3. After long-term use, the portion of the pot body 1 facing the heating tube 3 may be deformed, resulting in an increase in the gap between the portion and the heating plate 4. In this embodiment, one of the heating plates 4 is arranged to float relative to the other heating plate 4, so that when the pot body 1 is deformed, the corresponding heating plate can continue to fit the deformed portion of the pot body by floating, so that the heat generated by the heating plate can be conducted to the pot body 1 through direct contact with the pot body 1, thereby improving the heat transfer performance and thermal efficiency, making the food heated more evenly, not only reducing the probability of the bottom of the pot body 1 being burnt during cooking, but also improving the cooking taste of the food, thereby improving the user experience.
[0052] Specifically, a reflective cover adapted to the shape of the bottom of the pot body 1 is provided at the bottom of the pot body 1, and mounting positions corresponding to the number of heating plates 4 are provided on the reflective cover, and an elastic support member is provided between the reflective cover and the heating plate 4 so that the heating plate 4 can float relative to the reflective cover to fit with the bottom of the pot body 1.
[0053] As a preferred example under this embodiment, Figure 1 , Figure 3 As shown, the pot body 1 has two cooking cavities 11, and the heating device includes a left heating plate 41 and a right heating plate 42 distributed on the left and right. This example does not limit the symmetry of the left heating plate 41 and the right heating plate 42, as long as the shape of the heating plate 4 matches the shape of the bottom of the cooking cavity 11. If the shapes of the two cooking cavities 11 projected toward the heating device are two symmetrically distributed rectangles, the left heating plate 41 and the right heating plate 42 can be set as two symmetrically distributed rectangular structures; if the shapes of the two cooking cavities 11 projected toward the heating device are two symmetrically distributed semicircles, the left heating plate 41 and the right heating plate 42 can be set as two symmetrically distributed semicircular structures.
[0054] As another example under this embodiment, the pot body 1 has three cooking cavities, namely a central cooking cavity and a left cooking cavity and a right cooking cavity arranged around the central cooking cavity and located on the left and right sides of the central cooking cavity respectively. Correspondingly, the heating device includes a left heating plate and a right heating plate distributed on the left and right sides, and a central heating plate wrapped between the left heating plate and the right heating plate. The left heating plate, the right heating plate and the central heating plate in this example can all float to fit the pot body parts corresponding to their positions respectively.
[0055] Implementation method 2: Figure 4As shown, the heating device includes a heating plate 4, and a plurality of heating zones 2 are formed on the heating plate 4. In this way, only one heating plate is needed to provide a plurality of heating zones 2, and during the assembly process, only one heating plate needs to be installed to achieve the installation of a plurality of heating zones 2, which reduces the difficulty of assembling the heating plate and helps to improve the assembly efficiency of the cooking appliance.
[0056] As a preferred embodiment of the second implementation mode, Figure 4 As shown, two heating zones 2 are provided on the heating plate 4 in the left-right direction, and the heating tubes 3 on the two heating zones 2 are arranged symmetrically. With such arrangement, after completing the installation of the heating tube 3 in one heating zone 2, the assembler can refer to the installation position of the installed heating tube 3 to install the heating tube 3 in another heating zone 2, which helps to improve the assembly efficiency of the assembler.
[0057] As a preferred example under this embodiment, Figure 4 As shown, the cold end sections 32 of the heating tubes 3 on the two heating partitions 2 are located on the inner sides of the two heating partitions 2. With this arrangement, the cold end sections 32 of the two heating partitions 2 are concentrated in the central area of the heating device, further improving the uniformity of the heat provided by the heating device, avoiding the high concentration of heat in the central area of the heating device, thereby reducing the probability of the central area of the heating plate 4 being deformed by heat, ensuring the effective fit of the heating plate 4 with a large area of the bottom of the pot body 1, and thus ensuring the heat transfer efficiency.
[0058] The second embodiment does not limit the connection method between the heating tube 3 and the heating plate 4, and any one of the following embodiments may be adopted:
[0059] Embodiment 1: The heating plate 4 and the heating tube 3 are formed separately, and a fixing buckle for fixing the heating tube 3 is provided on the heating plate 4, and the heating tube 3 is buckled to the heating plate 4 through the fixing buckle.
[0060] Embodiment 2: The heating plate 4 and the heating tube 3 are formed separately, and the heating tube 3 is fixedly connected to the heating plate 4 by welding or other methods.
[0061] Embodiment three: The heating plate 4 and the heating tube 3 are integrally cast, and a material injection port 43 surrounded by a plurality of the heating partitions 2 is provided in the center of the heating plate 4. Integrally casting the heating plate 4 and the heating tube 3 eliminates the process of assembling the heating plate 4 and the heating tube 3, which helps to increase the production rate of the heating device; a material injection port 43 surrounded by a plurality of heating partitions 2 is provided in the center of the heating plate 4, which fully utilizes the redundant space in the center of the heating plate 4, reduces the spatial impact of the material injection port 43 on each heating partition 2, and optimizes the structural design of the heating plate 4. This embodiment three does not limit the casting form, which can be either die casting or casting.
[0062] Anything not described in this application can be achieved by adopting or drawing on existing technologies.
[0063] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.
