The bottom of cooking utensils such as traditional rice cooker adopts modes such as dish or IH drum of generating heat to heat for the heat that produces is concentrated in the bottom more. In the cooking process, especially when the food in the inner pot is full, the problem of half-cooked food is easily caused due to uneven heating of the food, even the bottom of the inner pot is burnt, but the upper layer of the food is still half-cooked.

In order to solve the above problems, the present invention provides a cooking appliance, which can be but not limited to an electric cooker, a pressure cooker, a food processor, etc. Referring to fig. 1 to 8, embodiments of a cooking device according to the present invention are shown in the drawings.

Referring to fig. 1 to 4, the cooking apparatus 1 of the present invention includes a cooking base 10, a lid assembly 20 and an electromagnetic heating device 30.

The cooking seat 10 generally includes a casing, which may be configured to have any suitable shape, size and material according to actual needs, for example, the casing may be configured to be substantially cylindrical, prismatic or spherical; the material of making of casing can set up to metal material or plastics material etc..

The cooking seat 10 has a cavity with an opening at one end. It will be appreciated that the housing may directly define the cavity; alternatively, the cooking base 10 comprises a housing defining a mounting cavity and a pan body 120 mounted in the mounting cavity and defining the cavity.

The lid assembly 20 is openably and closably disposed at an open end 111 of the cooking base 10 to form a cooking cavity 110 together with the cooking base 10. It is understood that the lid assembly 20 can be openably and closably provided to the cooking receptacle 10 in any suitable movable manner. For example, a side edge of the lid assembly 20 is rotatably mounted to the open end 111 of the cooking receptacle 10, so that the lid assembly 20 can be turned around the side edge to open and close the opening of the cavity. Alternatively, the middle portion of the lid assembly 20 may be rotatably mounted to the open end 111 of the cooking seat 10 by a rotating shaft, so that the lid assembly 20 can rotate around the rotating shaft to open and close the opening of the cavity. Alternatively, the lid assembly 20 can move in translation, specifically in sliding translation or rolling translation, relative to the open end 111 of the cooking base 10, so as to open and close the opening of the cavity.

When the lid assembly 20 is moved to close the cavity, i.e. cover the opening, the lid assembly 20 and at least the open end 111 of the cooking base 10 are in sealing engagement, and together enclose a substantially closed cooking cavity 110 (which may reserve, for example, a steam overflow hole).

The orientation of the upper opening 111 of the cooking base 10 is not limited by the design, so that the lid assembly 20 can be disposed on any side of the cooking base 10 according to actual requirements when the cooking base 10 is fixed on any platform, for example, on the top side, any side or even the bottom side of the cooking base 10. For the sake of understanding, in the following embodiments, the cooking utensil 1 is installed along the vertical direction, that is, the vertical direction, and the cooking base 10 and the lid assembly 20 are sequentially arranged from bottom to top, and the opening faces upward.

Referring to fig. 6 to 8, the electromagnetic heating device 30 includes a first coil panel 310 disposed on the lid assembly 20 and a second coil panel 320 disposed on a side of the cooking receptacle 10, the first coil panel 310 is used for heating the top of the cooking cavity 110 when being powered on, and the second coil panel 320 is used for heating the side of the cooking cavity 110 when being powered on; wherein the first coil disk 310 and the second coil disk 320 are operatively coupled.

In the technical solution provided by the present invention, the first coil panel 310 disposed on the lid assembly 20 can heat the top of the cooking cavity 110, the second coil panel 320 disposed on the side of the cooking base 10 can heat the side of the cooking cavity 110, and by combining the heating component (i.e. the third coil panel 330) disposed on the bottom of the cooking base 10, a three-dimensional heat circulation system can be formed in the cooking cavity 110, so as to ensure that the food in the cooking cavity 110 is uniformly heated in all directions, which is helpful for improving the cooking effect; the first coil panel 310 and the second coil panel 320 both use the electromagnetic heating principle, and can form larger area heating and more uniform heat conduction compared with heating methods such as resistance wires and the like; the first coil plate 310 and the second coil plate 320 are arranged in a linkage operation manner, so that the integral heating of the upper area of the cooking cavity 110 can be completed immediately, the temperature difference between the upper part and the lower part of the cooking cavity 110 is reduced, the formation of condensed water in the upper area of the cooking cavity 110 is avoided, and the problems that the food is dripped or undercooked, and the food and the taste are influenced due to the fact that the condensed water generated at the side part of the cover assembly 20 or the cooking cavity 110 falls back on the food (such as rice) in the cooking cavity 110 in the cooking process are solved effectively; meanwhile, the phenomenon that condensed water generated at the position of the pot cover assembly 20 or the side part of the cooking cavity 110 drops on rice and drips on the cooking base 10 in the opening process of the pot cover assembly 20 to pollute the cooking base 10 or seep into the cooking base 10 to damage an electric control device in the cooking base 10 is effectively avoided.

It can be understood that there are various ways to realize the linked operation of the first coil panel 310 and the second coil panel 320, for example, in an embodiment, the cooking appliance 1 further includes a control unit, the control unit is electrically connected to the first coil panel 310 and the second coil panel 320 respectively, the control unit can be used to control not only the power on and power off of the first coil panel 310 and the second coil panel 320, but also to realize the substantially synchronous start and the substantially synchronous stop of the first coil panel 310 and the second coil panel 320 through time control.

Alternatively, in an embodiment, the cooking appliance 1 further includes a control circuit, and the first coil panel 310 and the second coil panel 320 are connected in series to the same control circuit, so that when the control circuit is turned on, the first coil panel 310 and the second coil panel 320 are powered on substantially simultaneously to start; conversely, when the control circuit is turned off, the first coil plate 310 and the second coil plate 320 are substantially simultaneously de-energized and stopped. By connecting the first coil panel 310 and the second coil panel 320 in series, not only can the purpose of the series-connection operation of the first coil panel 310 and the second coil panel 320 be realized, but also the simplification of the whole structure and the reduction of the whole cost are facilitated.

Further, based on any of the embodiments described above, the inductance of the first coil disk 310 is larger than the inductance of the second coil disk 320. It can be understood that when the cooking appliance 1 is operated, the steam generated in the cooking cavity 110 naturally rises upwards, so that more steam is condensed on the lid assembly 20 to form condensed water, and part of the steam is condensed on the side of the cooking cavity 110 to form condensed water. By setting the inductance of the first coil disk 310 to be greater than the inductance of the second coil disk 320, so that the operating power of the first coil disk 310 is greater than the operating power of the second coil disk 320 in the power-on state, the first coil disk 310 can heat the top of the cooking cavity 110 to a desired temperature more quickly than the second coil disk 320. In addition, since the lid assembly 20 abuts against the open end 111 when the lid assembly 20 closes the open end 111, when the first coil panel 310 is heated to a desired temperature faster than the second coil panel 320, heat can be conducted to the side of the cooking cavity 110 through the abutting portion between the lid assembly 20 and the open end 111, which assists the second coil panel 320 in heating the side of the cooking cavity 110, thereby achieving a better heating effect.

Based on the above, in one embodiment, when the first coil disk 310 is connected in series with the second coil disk 320; the inductance of the first coil disk 310 and the second coil disk 320 after being coupled in series is L, the inductance of the second coil disk 320 is L2, and the ratio of L2 to L is not less than 30% and not more than 50%. It can be understood that the coil panel generally includes a panel seat and a coil winding, and the winding area and the number of winding layers of the coil winding both affect the inductance of the coil panel. When the ratio between L2 and L is much less than 30%, it is equivalent to increase the inductance of the first coil disk 310 or weaken the inductance of the second coil disk 320 as much as possible, which increases the space occupation of the first coil disk 310 and weakens the function of the second coil disk 320; conversely, when the ratio between L2 and L is much greater than 50%, it is equivalent to increasing the inductance of the second coil plate 320 or weakening the inductance of the first coil plate 310 as much as possible, which increases the space occupation of the second coil plate 320. Therefore, setting the ratio of L2 to L to be not less than 30% and not more than 50% enables a balance to be obtained in the structural size of the first coil disk 310 and the second coil disk 320, and in the heating function.

It should be noted that, in other embodiments, the inductance of the second coil panel 320 may also be set to be greater than the inductance of the first coil panel 310, so as to enhance the heating power of the side portion of the cooking cavity 110, so that the food in the cooking cavity 110 is sufficiently and uniformly heated in all directions, which is not described herein again.

Based on any of the above embodiments, referring to fig. 5 and 8, the electromagnetic heating apparatus 30 further includes a third coil panel 330, and the third coil panel 330 is disposed at the bottom of the cooking base 10 to heat the bottom of the cooking cavity 110 when being powered on.

The third coil 330 is a main heating unit of the cooking appliance 1, and mainly heats the bottom of the cooking cavity 110. In design, the third coil 330 may be disposed at the bottom of the cooking base 10, such that the third coil 330 is closer to the bottom of the cooking cavity 110, which helps to reduce energy consumption of the third coil 330 and simplify the structure of the whole machine under the same heat supply, and helps to stabilize the whole machine by making the center of gravity of the whole machine lower. Of course, in other embodiments, the third coil 330 may be disposed on any side of the lower region of the cooking base 10 to conduct heat to the bottom of the cooking chamber 110.

Of course, for the third coil panel 330 and the cooking utensil 1 to operate well, the cooking utensil 1 generally further includes a control device 130, and the control device 130 is generally disposed on the cooking base 10 and can be electrically connected to the third coil panel 330 to provide the third coil panel 330 with power and required control signals. The control device 130 can be used as a main control system of the cooking appliance 1, which is a mature technology and is not described herein again.

In addition, the cooking appliance 1 may further include a temperature measuring component 140, and the temperature measuring component 140 is disposed at the bottom of the cooking seat 10 and is used for measuring the temperature of the bottom of the cooking cavity 110. The temperature measuring assembly 140 is electrically connected to the control device 130, so that the control device 130 can adjust the operating parameters of the third coil panel 330 according to the operating state and the measurement data of the temperature measuring assembly 140. The temperature measuring component 140 is also the prior art and is not described in detail.

Further, in one embodiment, the first coil panel 310 and the second coil panel 320 are connected in series to form a first heating unit, for example, to form a control circuit, and the third coil panel 330 forms a second heating unit, for example, to form another control circuit; the first heating unit and the second heating unit can operate independently of each other. Thus, the second heating unit is used as the main heating unit of the cooking appliance 1, and can work as required at any time, so that the purpose of cooking food materials is achieved; and the first heating unit assists the second heating unit to heat the food and is used for eliminating condensed water at the top and side of the cooking cavity 110, and the use frequency and power requirements are relatively lower than those of the second heating unit. The first heating unit and the second heating unit are operated independently, so that the purposes of energy conservation and consumption reduction can be achieved, and the heating work of the cooking appliance 1 is more diverse and flexible.

Furthermore, in an embodiment, the second coil disk 320 has a proximal coil segment 321 near the open end 111; at least the proximal coil segment 321 of the second coil disc 320 is arranged near the open end 111. It can be understood that the second coil 320 is arranged to heat mainly the side portion of the cooking cavity 110, and since the cooking cavity 110 is generally defined by the pot body 120 and the lid assembly 20 arranged on the cooking base 10, that is, the bottom and the side portion of the cooking cavity 110 are integrally arranged, so that when the third coil heats the bottom of the cooking cavity 110, the heat thereof is gradually conducted toward the side portion, so that the side portion of the cooking cavity 110, especially the lower region, that is, the region far away from the open end 111 has a certain amount of heat, therefore, by arranging the proximal coil section 321 of the second coil 320 close to the open end 111, at least the upper region of the side portion of the cooking cavity 110 can be ensured to be heated.

It will be appreciated that the second coil form 320 also has a distal coil section distal to the open end 111. When the proximal coil segment 321 is ensured to be close to the open end 111, the distal coil segment can be arranged to be close to or far from the open end 111 according to actual needs; that is, the second coil panel 320 may be disposed to be entirely at an upper area of the side of the cooking chamber 110, or dispersed throughout the entire area of the side of the cooking chamber 110. The coil windings of the second coil plate 320 may be arranged in a single loop or multiple loops.

Further, in an embodiment, the electromagnetic heating device 30 further includes an annular disc seat 340, and the annular disc seat 340 surrounds along a peripheral side of the cooking cavity 110. The annular disc seat 340 may be integrally formed with the housing structure of the cooking base 10. Alternatively, the annular plate base 340 may be separately disposed from the casing structure of the cooking base 10, and may be screwed, fastened, adsorbed, or bonded to the cooking base 10. The second coil disk 320 is located on a side of the annular disk seat 340 facing away from the cooking chamber 110. The annular disk seat 340 may be fixedly connected to the disk seat of the second coil disk 320, or the annular disk seat 340 may directly form the disk seat of the second coil disk 320, so that the coil winding of the second coil disk 320 is wound. The annular tray 340 is disposed to separate the second coil panel 320 or the coil winding thereof from the cooking cavity 110 (or the pot body 120) and maintain a certain distance, so that the second coil panel 320 can heat the side of the cooking cavity 110 (or the pot body 120) and also can perform a certain heat insulation function.

Based on any of the above embodiments, in the present design, the lid assembly 20 includes a lid main body 210. The pot cover main body 210 includes a cover plate 215 provided at one side of the pot cover main body 210. The lid body 210 in this design is substantially in the shape of a block or a plate with a certain thickness adapted to the shape, size and material of the cooking base 10. The lid body 210 has a bottom side facing the open end 111 of the cooking receptacle 10 and a top side facing away from the open end 111 of the cooking receptacle 10. The cover plate 215 is formed on the bottom side of the lid main body 210, is disposed toward the open end 111, and surrounds the cooking cavity 110 together with the cavity of the cooking base 10 when the open end 111 is closed.

It is understood that the cover plate 215 is made of a heat conductive material, such as metal. In a specific application, the cover plate 215 may be a flat plate-shaped structure, and is adapted to the shape and size of the opening to be disposed right covering the opening; of course, in other embodiments, at least one side of the cover plate 215 facing the opening may be configured to have a curved surface shape, for example, the curved surface gradually protrudes toward the cooking seat 10 from the edge of the cover plate 215 to the center of the cover plate 215, or gradually dents away from the cooking seat 10 from the edge of the cover plate 215 to the center of the cover plate 215; alternatively, the cover plate 215 may be integrally concave, and have a plate-shaped body and a peripheral sidewall protruding from the periphery of the plate-shaped body in a direction toward the cooking receptacle 10, and thus, the first coil plate 310 may be disposed only corresponding to the plate-shaped body, or disposed corresponding to the plate-shaped body and the peripheral sidewall, respectively, so that when the first coil plate 310 is operated, heat may directly act on the plate-shaped body and directly or indirectly act on the peripheral sidewall, thereby realizing three-dimensional heating of the upper region of the cooking cavity 110.

The pot lid main body 210 generally further includes a lid 211, the lid 211 is disposed on a side of the cover plate 215 opposite to the cooking base 10, the lid 211, the first coil plate 310 and the cover plate 215 are sequentially stacked, and the lid 211 and the cover plate 215 together limit the first coil plate 310. The cover 211 may be disposed in a plate shape and opposite to the cover plate 215. Or, a receiving groove is concavely formed at the lower end of the cover body 211, and the first coil panel 310 and the cover plate 215 are received by the receiving groove, so that the pot cover assembly 20 has a compact structure and is more attractive.

Next, the pot lid main body 210 may further include a partition 213, and the partition 213 is disposed between the cover plate 215 and the cover body 211. The partition 213 and the cover 211 together sandwich and limit the first coil disk 310. It should be noted that, when the cover 211 is specifically designed with the receiving groove, the area between the cover plate 215 and the cover 211 refers to the area between the bottom of the receiving groove and the cover plate 215.

The partition 213 is connected to the cover 211. Specifically, the partition 213 may be directly connected to the cover 211, for example, by welding, screwing, snapping, adhering, or adsorbing to the side wall of the receiving groove. Alternatively, the pot cover main body 210 may further include a mounting bracket 214, and the mounting bracket 214 is used for mounting the partition plate 213 and is connected to the cover body 211. Specifically, referring to fig. 3 and 6, the mounting bracket 214 is substantially annular and has an annular supporting surface for supporting and fixing the partition plate 213, and the annular supporting surface is disposed toward the first coil disk 310. The mounting bracket 214 may be mounted on the side groove wall of the accommodating groove by welding, screwing, snapping, adhering, or adsorbing, for example.

When the pot lid main body 210 is provided with the mounting bracket 214 as described above, the mounting bracket 214 is connected to the lid body 211, and connects the lid body 211, the first coil panel 310, and the partition plate 213 into a single body. The cover plate 215 may be mounted on a side of the mounting bracket 214 opposite to the partition 213 and detachably connected to the mounting bracket 214. Thus, in practical applications, the cover plate 215 may be removed according to actual needs, for example, to perform maintenance replacement, disassembly and assembly cleaning, and the like, and the partition plate 213 may perform a good isolation and protection function on at least the first coil panel 310, so as to prevent the disassembly and assembly process of the cover plate 215 from affecting the use of the first coil panel 310 or causing harm to users.

Based on the above, further, at least the part of the partition 213 corresponding to the first coil panel 310 is provided with a visualization structure. The visualization structure may be embodied as a transparent window made of glass, a transparent film layer, or the like, or as a display surface that represents the image information at the first coil disk 310 by a principle such as reflection, refraction, or the like. For example, in the present embodiment, in order to simplify the structure and reduce the cost, the whole partition plate 213 may be made of a glass material, which not only achieves the visualization purpose, but also provides a certain uniform and thermal insulation effect for the heat applied to the cover plate 215 via the first coil disk 310.

In addition, since the first coil disk 310 needs to inductively generate heat in a power-on state. Therefore, the lid assembly 20 generally further includes an electric control component 230, and the electric control component 230 is electrically connected to the first coil panel 310, and provides a power supply for the first coil panel 310, and also provides a preset control signal according to actual needs. The electronic control unit 230 is, for example, an integrated circuit board. The electric control component 230 may be separately disposed from the control device 130, specifically, for example, independently disposed on the lid body 210 or on the cooking seat 10; of course, the electronic control component 230 may also be integrated with the control device 130 to form a part of the control device 130.

In practical applications, the cooking appliance 1 generally further includes a display panel, the display panel provides a control interface and/or a display interface, and the display panel can be disposed at the upper end of the lid assembly 20, that is, the lid body 211. For this reason, the electric control part 230 may be also installed at the cover 211. In order to reduce the mutual influence between the electric control part 230 and the first coil panel 310, in an embodiment, the pot lid main body 210 further includes a shielding plate 212, and the shielding plate 212 is at least correspondingly disposed between the electric control part 230 and the first coil panel 310. The shield plate 212 may be specifically an aluminum plate or the like.

Based on any of the above embodiments, the lid main body 210 is provided with a through hole 216. The through hole 216 penetrates through the lid main body 210, and the through hole 216 can exchange substances inside and outside the cooking cavity 110, for example, discharge steam generated in the cooking cavity 110 through a cooking process to the outside of the cooking cavity 110, or throw food materials and the like outside the cooking cavity 110 into the cooking cavity 110. Therefore, according to the actual requirement of the cooking appliance 1, the through hole 216 can be used as a communication hole 216, such as a steam overflow hole of the cooking cavity 110, a feeding hole of materials (such as food materials, seasonings, water, etc.), a heat dissipation hole, a pressure relief hole, etc.

Of course, since the through hole 216 communicates with the inside and outside environment of the cooking cavity 110, in an embodiment, when the lid assembly 20 further includes a functional component, the through hole 216 may also serve as a mounting hole or a relief hole for the functional component. Specifically, the functional component is detachably connected to the lid main body 210, and the connection between the functional component and the lid main body 210 may be located at any position of the lid main body 210. Moreover, at least a part of the functional component is disposed through the through hole 216, and may be completely accommodated in the through hole 216, or may pass through the through hole 216 and extend into the cooking cavity 110. Therefore, other hole structures do not need to be additionally arranged on the functional part, which is beneficial to simplifying the processing technology and ensuring the structural strength of the pot cover main body 210.

The functional components can be set to be different according to actual needs:

in an embodiment, when the cooking appliance 1 is a product such as a cooker, etc. and is provided with a stirring function, the functional component may be a stirring mechanism, which at least includes a stirring shaft and a stirring blade connected to the stirring shaft, and in this case, the stirring shaft may pass through the through hole 216 and install the stirring blade in the cooking cavity 110.

In an embodiment, when the cooking appliance 1 is a product such as an automatic food processor, and is provided with an automatic feeding function, a material crushing function, and the like, the functional component may be a feeding mechanism, such as an air blowing or air extracting mechanism, a conveyor belt mechanism, and the like; the functional component may also be a piercing mechanism, such as a capsule-piercing knife, a rice-breaking roller, etc.

In one embodiment, the functional component may also be a sensing mechanism, such as a temperature detector 220, a humidity sensor, a pressure sensor, and the like.

In view of the above, the pot lid main body 210 may further include a steam valve assembly 217, and the steam valve assembly 217 is connected to the lid body 211 and movably installed at the through hole 216 to control the opening of the through hole 216.

In addition, based on any of the above embodiments, the lid main body 210 is provided with a mounting groove 218. The cover plate 215 is covered at the notch of the mounting groove 218, and when the cover plate 215 completely closes the mounting groove 218, the mounting groove 218 is in a completely closed state; when the cover 211 is provided with the air hole communicating with the mounting groove 218, the steam in the cooking cavity 110 can enter the mounting groove 218 through the air hole, so that the mounting groove 218 can communicate with the inside of the cooking cavity 110 while being disconnected from the external environment of the cooking base 20.

When the pot cover assembly 20 further includes the temperature detector 220, the temperature detector 220 may be selectively installed at the through hole 216 and/or the installation groove 218. For example, when the thermometers 220 are provided as one, they may be installed at the through hole 216 or at the installation groove 218; when the temperature detectors 220 are two, or the same temperature detector 220 has two temperature measuring points, the two temperature detectors 220 or the two temperature measuring points can be arranged at the through hole 216 and the mounting groove 218, so that more and richer measuring results can be provided, and the measurement accuracy can be facilitated.

In one embodiment, the temperature detector 220 is disposed at the mounting groove 218, and a temperature measuring end of the temperature detector 220 can abut against the cover plate 215 or face the cover plate 215 and keep a distance from the cover plate 215. When the cover 215 is provided with the air hole communicated with the cooking cavity 110 such that the mounting groove 218 is semi-closed, more high temperature steam can be accumulated, thereby preventing the high temperature steam from flowing out of the cooking cavity 110. Therefore, the temperature detector 220 is disposed at the mounting groove 218, and has a better and more accurate measurement effect for sensing the temperature variation in the cooking process in the cooking cavity 110. Further, the mounting groove 218 may be disposed as close to the center of the lid main body 210 as possible. Since the steam in the cooking chamber 110 is concentrated in the middle and ascends upward, the temperature detector 220 disposed near the center can receive more and more original steam, thereby contributing to accurate measurement. The through hole 216 is disposed beside the mounting groove 218, so as to prevent steam at the through hole 216 from overflowing or prevent the functional components from being mounted to interfere with the measurement process or result of the temperature detector 220. Of course, the temperature measurer 220 may directly measure the temperature of the steam in the mounting groove 218, or may obtain the temperature of the cooking chamber 110 by measuring the temperature of the cover plate 215 and converting the measured temperature when the steam is attached to the cover plate 215.
