TECHNICAL FIELD
[0001] The utility model relates to the technical field of household appliances, specifically relates to a cooking utensil. BACKGROUND
[0002] At present, in the cooking utensil of electromagnetic heating, the heating of the food material in the inner container is realized through the magnetic field action between the coil and the inner container, but the position of the coil relative to the inner container in the related technology is fixed, and the adjustment of the heating power can only be controlled through the on-off of the coil, so that the temperature fluctuation of the food material in the inner container during the cooking process is large, which is not conducive to improving the cooking effect. At the same time, in the related technology, the user cannot intuitively observe the state of the coil disc, so as to monitor the working state of the coil disc. SUMMARY
[0003] The utility model aims at least to solve one of the technical problems existing in the prior art or related technology.
[0004] Therefore, the utility model provides a cooking utensil.
[0005] Therefore, the utility model provides a cooking utensil.
[0006] The cooking appliance provided by this utility model includes a shell, a support base, a heating container, a coil, and a drive assembly. The support base is disposed inside the shell to support the heating container. A coil is wound on the coil. When the coil on the coil is energized, it generates a magnetic field. The heating container heats up under the influence of the magnetic field, thus cooking the food inside. The drive assembly is in contact with the coil and can drive the coil to move relative to the heating container during the cooking process, thereby adjusting the distance between the coil and the heating container. During this movement, the magnetic field generated by the coil moves relative to the heating container, causing a change in the intensity of the induced magnetic field in the heating container. In other words, by adjusting the distance between the coil and the heating container during cooking, the coupling between them is adjusted, thereby regulating the heating power of the cooking appliance. This allows for a smooth temperature transition during cooking, reducing temperature fluctuations and improving the cooking effect. At least a portion of the support base is a light-transmitting structure, and at least a portion of the coil is positioned opposite to the light-transmitting structure of the support base. Thus, when the heating container is removed, the user can visually observe the location and operation of the coil through the light-transmitting structure, thereby enabling the user to monitor whether the heating system is operating normally.
[0007] The cooking appliance provided by this utility model may also have the following additional technical features:
[0008] In some embodiments, the support may optionally include: a base; at least one viewing window disposed on the base, the viewing window being a light-transmitting structure, and the coil disk being at least partially disposed opposite to the viewing window.
[0009] In this embodiment, the support base includes a base body and at least one viewing window. The viewing window is a light-transmitting structure, allowing the support base to be seen through the viewing window. The coil is at least partially positioned opposite the viewing window, allowing the user to observe the coil through the viewing window when the heating container is removed, thus enabling visualization of the coil.
[0010] In some embodiments, the base may optionally have at least one through hole, and a viewing window may be provided in the through hole.
[0011] In this embodiment, a through hole is provided on the base, and the viewing window is placed at the through hole to facilitate the installation of the viewing window.
[0012] In some embodiments, optionally, a through hole is provided on the bottom wall of the base, and the coil is at least partially located at the bottom of the base.
[0013] In this embodiment, the coil is optionally located at least partially at the bottom of the base to reduce the space occupied on the side of the cooking appliance and to improve the heating uniformity of the food in the heating container. Correspondingly, the through hole is located on the bottom wall of the base to help ensure the strength of the base. At the same time, this arrangement also makes it easier for the user to observe the position and working status of the coil.
[0014] In some embodiments, the viewing window may optionally include a plastic component or a glass component.
[0015] In this embodiment, the viewing window can be a structure such as a plastic part or a glass part that can achieve visibility without being heated by the magnetic field of the coil.
[0016] In some embodiments, the window and the base may be connected by any of the following methods: adhesive, snap-fit, or screw connection; or the window and the base may be an integral structure.
[0017] In this embodiment, the viewing window and the base are connected by adhesive, snap-fit, or screw connection to facilitate the assembly and disassembly of the viewing window and the base. The viewing window and the base can also be designed as an integral structure to reduce assembly steps and improve the sealing of the connection between the viewing window and the base to prevent leakage from the connection gap or to prevent impurities from entering the connection gap and making cleaning difficult.
[0018] In some embodiments, optionally, when there are multiple viewable windows, the multiple viewable windows are spaced apart around the center of the base.
[0019] In this embodiment, when there are multiple viewing windows, the multiple viewing windows are spaced apart around the center of the base body, thereby increasing the visible area of the coil disk.
[0020] In some embodiments, optionally, a display section is provided on the side of the coil facing the light-transmitting structure, and the display section is disposed opposite to the light-transmitting structure.
[0021] In this embodiment, a display section is provided on the side of the coil facing the light-transmitting structure, and the display section is positioned opposite to the light-transmitting structure, thereby making the coil more visible under the viewing window.
[0022] In some embodiments, the drive assembly can optionally drive the coil to move up and down between a first position close to the heating container and a second position far from the heating container.
[0023] In this embodiment, the driving component moves the coil relative to the heating container up and down between a first position and a second position. This allows the magnetic field generated by the coil to gradually move closer to or further away from the heating container, changing the distance between them and thus altering the coupled magnetic field. This enables stepless adjustment of the heating power of the cooking appliance. Furthermore, adjusting the distance between the coil and the heating container by moving the coil up and down is relatively simple, reducing the manufacturing difficulty of the driving component.
[0024] In some embodiments, the distance between the first position and the second position may be greater than 0 mm and less than or equal to 100 mm.
[0025] In this embodiment, the lifting range of the coil is set to be greater than 0 mm and less than or equal to 100 mm, which can reduce the impact of the lifting of the coil on the overall height of the cooking appliance, while ensuring the adjustable range of heating power.
[0026] In some embodiments, the drive assembly may optionally include: a drive part; a motion part connected to the drive part; a first mating part is provided on the motion part, and a second mating part is provided on the coil disk; the first mating part contacts the second mating part; the drive part can drive the motion part to rotate; and the first mating part rotates relative to the second mating part to make the coil disk rise and fall.
[0027] In this embodiment, the driving assembly includes a driving part and a moving part. The moving part has a first mating part, and the coil has a second mating part. The first mating part and the second mating part are in contact. The driving part can drive the moving part to rotate. During the rotation of the moving part, the first mating part rotates relative to the second mating part. With the cooperation of the first and second mating parts, the coil with the second mating part rises and falls, thereby changing the distance between the coil and the heating container. This adjusts the coupling between the coil and the heating container during cooking, thus regulating the heating power of the cooking appliance. In other words, this application converts the rotation of the moving part into the rising and falling of the coil, reducing the overall space occupied by the driving assembly in the height direction of the cooking appliance.
[0028] In some embodiments, optionally, one of the first mating portion and the second mating portion includes a first protrusion and a first recess, the first protrusion and the first recess are alternately arranged along the rotation direction of the moving portion, and the other of the first mating portion and the second mating portion can alternately engage with the first protrusion and the first recess to make the coil disk move up and down between the first position and the second position.
[0029] In this embodiment, the first and second mating parts achieve the switching between rotation and linear movement through a concave-convex structure. One of the first and second mating parts includes a first convex portion and a first concave portion. As the first mating part rotates with the moving part, the other of the first and second mating parts alternately passes through the first convex portion and the first concave portion, thereby realizing the reciprocating lifting and lowering of the coil. When the other of the first and second mating parts engages with the first convex portion, the first and second mating parts together lift the coil, bringing it closer to the heating container. When the other of the first and second mating parts engages with the first concave portion, the coil descends, moving it away from the heating container.
[0030] In some embodiments, optionally, one of the first mating part and the second mating part includes an inclined surface structure, the inclined surface structure being inclined relative to the axis of rotation of the moving part, and the other of the first mating part and the second mating part includes a slider structure, the slider structure being able to slide along the inclined surface structure as the moving part rotates, thereby driving the coil disk to rise and fall.
[0031] In some embodiments, the other of the first mating portion and the second mating portion may optionally include a second protrusion and a second recess, the second protrusion and the second recess being alternately arranged along the rotation direction of the moving portion.
[0032] In this embodiment, the other of the first mating part and the second mating part further includes a second convex part and a second concave part. The second convex part and the second concave part are alternately arranged along the rotation direction of the moving part, so that the second convex part and the second concave part alternately mate with the first convex part and the first concave part, thereby increasing the lifting range of the coil, thereby increasing the adjustable range of the heating power of the cooking appliance, and improving the driving stability between the coil and the moving part.
[0033] In some embodiments, optionally, the first protrusion and the first recess are connected sequentially along the rotation direction, or the first protrusion and the first recess are spaced apart along the rotation direction; and / or the second protrusion and the second recess are connected sequentially along the rotation direction, or the second protrusion and the second recess are spaced apart along the rotation direction; and / or the second mating part is located in the middle of the coil disk, the coil on the coil disk is located around the second mating part, or the second mating part is arranged radially towards the side wall of the coil disk, and the second mating part surrounds the coil on the coil disk.
[0034] In this embodiment, the first protrusion and the first concave portion are sequentially connected along the rotation direction of the moving part. This makes the movement of the coil smoother during the rotation of the moving part and allows the coil to continuously rise and fall with the continuous rotation of the moving part. Consequently, the induced magnetic field of the heating container changes continuously, increasing the adjustable range of heating power during cooking. Alternatively, the first protrusion and the first concave portion are spaced apart along the rotation direction, so that the rising and falling of the coil is not continuous, achieving intermittent rising and falling of the coil. Correspondingly, the second protrusion and the second concave portion can also be sequentially connected or intermittently arranged. Optionally, the second mating portion can be located in the middle of the coil to increase the winding area of the coil; the second mating portion can also be located in the radially outer part of the coil to increase the reliability and stability of the transmission.
[0035] In some embodiments, the driving part may optionally include a drive motor, and the moving part may include a first gear located on the side of the coil disk away from the support base. A first mating part is disposed on the first gear, wherein the drive motor is disposed in the middle of the first gear to drive the first gear to rotate. Alternatively, the moving part may also include a second gear connected to the drive motor, and the first gear meshes with the second gear.
[0036] In this embodiment, the driving unit includes a drive motor, and the moving unit includes a first gear. The drive motor is connected to the middle of the first gear, allowing the drive motor to directly drive the first gear to rotate, thus reducing the number of transmission components. Alternatively, the moving unit also includes a second gear, with the drive motor connected to the second gear. The first gear meshes with the second gear, and the drive motor drives the first gear to rotate via the second gear. In this way, the drive motor can be placed around the first gear, reducing the overall height of the cooking appliance. The cooking appliance proposed in this application achieves the lifting and lowering of the coil through the rotation of the drive motor and gear structure, making the lifting and lowering of the coil more stable and reliable. At the same time, converting rotation into lifting motion also reduces the space occupied by the drive components in the height direction.
[0037] In some embodiments, the cooking appliance may optionally further include: a rolling element disposed on at least one of the first mating portion and the second mating portion, the first mating portion and the second mating portion being in contact through the rolling element.
[0038] In this embodiment, the cooking appliance also includes a rolling element. The first mating part and the second mating part contact each other through the rolling element, so that the sliding friction between the first mating part and the second mating part is converted into rolling friction, thereby reducing the frictional resistance between the first mating part and the second mating part.
[0039] In some embodiments, the cooking appliance may optionally include at least one elastic element disposed between the support base and the coil, the elastic element being in a compressed state.
[0040] In this embodiment, the elastic element is in a compressed state. Under the action of the elastic element, the second mating part on the coil disk fits into the first mating part of the moving part, ensuring the stability and reliability of the drive assembly's drive of the coil disk. Furthermore, the elastic element is positioned between the support base and the coil disk, allowing it to limit the maximum stroke of the coil disk. This prevents the coil disk from colliding with the support base and causing damage to the support base, coil disk, or other components in the event of a problem with the drive assembly.
[0041] In some embodiments, optionally, a coil is wound around the outer wall of the support base, the coil on the support base can surround the heating container, and the coil on the support base can generate a magnetic field to heat the heating container when energized.
[0042] In this embodiment, a coil is wound around the outer wall of the support base, and the coil on the support base surrounds the heating container. When the coil on the support base is energized, the heating container can be heated. That is, both the coil on the coil disk and the coil on the support base can heat the heating container. Optionally, the coil on the coil disk and the coil on the support base can heat the heating container simultaneously, or the coil on the coil disk and the coil on the support base can heat the heating container separately.
[0043] In some embodiments, the cooking appliance may optionally include a control device connected to the drive assembly for controlling the drive assembly to operate in order to adjust the heating power of the cooking appliance by adjusting the distance between the coil and the heating container.
[0044] In this embodiment, the cooking appliance also includes a control device connected to the drive assembly for controlling the operation of the drive assembly. The control device controls the drive assembly to drive the coil to move, thereby adjusting the distance between the coil and the heating container, adjusting the coupling between the coil and the heating container, and thus adjusting the heating power of the cooking appliance.

Detailed Implementation
[0057] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0058] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0059] The following reference Figures 1 to 8 This invention describes a cooking appliance proposed according to some embodiments of the present invention.
[0060] like Figure 1 , Figure 2 and Figure 3 As shown, according to one embodiment of the present invention, a cooking appliance is provided, comprising: a housing 1; a support base 6 disposed within the housing 1, at least a portion of the support base 6 being a light-transmitting structure 62; a heating container 2 capable of being mounted on the support base 6; a coil 3 disposed on the outside of the support base 6 and at least partially opposite to the light-transmitting structure 62, the coil 3 having a coil wound on it, the coil on the coil 3 generating a magnetic field when energized to heat the heating container 2; and a driving assembly 4 connected to the coil 3 for driving the coil 3 to move relative to the heating container 2, thereby adjusting the distance between the coil 3 and the heating container 2 during the cooking process of the cooking appliance.
[0061] The cooking appliance provided by this utility model includes a shell 1, a support base 6, a heating container 2, a coil 3, and a drive assembly 4. The support base 6 is disposed inside the shell 1 to support the heating container 2. A coil is wound on the coil 3. When the coil on the coil 3 is energized, the coil on the coil 3 can generate a magnetic field. The heating container 2 heats up under the action of the magnetic field of the coil, thus cooking the food inside the heating container 2. The drive assembly 4 is in contact with the coil 3 and can drive the coil 3 to move relative to the heating container 2 during the cooking process to adjust the distance between the coil 3 and the heating container 2. In this way, during the movement of the coil 3 relative to the heating container 2, the magnetic field generated by the coil on the coil 3 moves relative to the heating container 2, causing a change in the intensity of the induced magnetic field in the heating container 2. That is, by adjusting the distance between the coil 3 and the heating container 2 during the cooking process, the coupling between the coil 3 and the heating container 2 is adjusted, thereby adjusting the heating power of the cooking appliance. In the cooking process, the temperature transition can be smoothly achieved by changing the heating power, reducing the temperature fluctuation amplitude during the cooking process and improving the cooking effect of the food. At least a portion of the support base 6 is a light-transmitting structure 62, and at least a portion of the coil 3 is arranged opposite to the light-transmitting structure 62 of the support base 6. Thus, when the heating container 2 is removed, the user can intuitively observe the location and operation of the coil 3 through the light-transmitting structure 62, realizing the visualization of the coil 3, so that the user can monitor whether the heating system is operating normally.
[0062] It is understood that at least a portion of the support 6 is a light-transmitting structure 62, including a portion of the support 6 being a light-transmitting structure 62 or the entire support 6 being a light-transmitting structure 62.
[0063] It should be noted that the movement of the coil 3 relative to the heating container 2 can adjust the distance between at least a part of the coil 3 and the heating container 2, thereby adjusting the power of the heating container 2. Specifically, the movement of the coil 3 can be lifting or lowering relative to the heating container 2 to move closer to or further away from the heating container 2, or it can be flipping or shaking relative to the heating container 2 to change the distance between at least a part of the coil 3 and the heating container 2, or it can be translating relative to the heating container 2 to adjust the positional relationship between the coil on the coil 3 and the heating container 2.
[0064] It is understandable that the position of the drive coil 3 relative to the heating container 2 changes gradually during the movement of the drive component 4, thus enabling the heating power of the cooking appliance to change gradually. In other words, the movement of the coil 3 allows the heating power of the cooking appliance to be infinitely adjustable, increasing the power adjustable range of the heating container 2. Consequently, during the cooking process, the heating power of the cooking appliance is smoothly adjusted, reducing temperature fluctuations and improving the cooking effect of the food.
[0065] Optionally, during the cooking process, the heating power required for each cooking stage is different. By moving the coil 3 relative to the heating container 2, the temperature between each cooking stage can be smoothly transitioned during continuous heating, thereby improving the cooking effect of the ingredients.
[0066] Optionally, the heating container 2 includes a magnetic pot or a pot body with a magnetic layer.
[0067] Optionally, the drive component 4 can drive the coil disk 3 to stop at any position within the movable range or drive the coil disk 3 to reciprocate within the movable range, thereby achieving stepless adjustment of the heating power.
[0068] like Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the support base 6 includes: a base body 64; at least one viewing window 620 disposed on the base body 64, the viewing window 620 being a light-transmitting structure 62, and the coil disk 3 being at least partially disposed opposite to the viewing window 620.
[0069] In this embodiment, the support base 6 includes a base body 64 and at least one viewing window 620. The at least one viewing window 620 is a light-transmitting structure 62, thereby making the support base 6 visible through the viewing window 620. The coil 3 is at least partially disposed opposite to the viewing window 620. When the heating container 2 is removed, the user can observe the coil 3 through the viewing window 620, thus making the coil 3 visible.
[0070] In some embodiments, the base 64 may optionally have at least one through hole 640, and a viewing window 620 may be disposed in the through hole 640.
[0071] In this embodiment, a through hole is provided on the base 64, and the viewing window 620 is disposed at the through hole 640 to facilitate the installation of the viewing window 620.
[0072] In some embodiments, optionally, a through hole 640 is provided on the bottom wall of the base 64, and the coil 3 is at least partially located at the bottom of the base 64.
[0073] In this embodiment, the coil 3 is at least partially disposed at the bottom of the base 64 to reduce the space occupied on the side of the cooking appliance and to improve the heating uniformity of the food in the heating container. Correspondingly, the through hole 640 is disposed on the bottom wall of the base 64, which helps to ensure the strength of the base 64. At the same time, this arrangement also makes it easier for the user to observe the position and working status of the coil 3.
[0074] Optionally, the viewing window 620 and the through hole 640 are sealed together to prevent water leakage from the gap between the through hole 640 and the viewing window 620.
[0075] In some embodiments, the viewing window 620 may optionally include a plastic component or a glass component.
[0076] In this embodiment, the viewing window 620 can be a structure such as a plastic part or a glass part that can achieve visibility without being heated by the magnetic field of the coil disk 3.
[0077] In some embodiments, the view window 620 and the base 64 may be connected by any of the following methods: adhesive, snap-fit, or screw connection; or the view window 620 and the base 64 may be an integral structure.
[0078] In this embodiment, the viewing window 620 and the base 64 are connected by adhesive, snap-fit, or screw connection to facilitate the assembly and disassembly of the viewing window 620 and the base 64. Alternatively, the viewing window 620 and the base 64 can be designed as an integral structure to reduce assembly steps and improve the sealing of the connection between the viewing window 620 and the base 64, preventing leakage from the connection gap or preventing impurities from entering the connection gap and making cleaning difficult.
[0079] In some embodiments, optionally, when there are multiple viewable windows 620, the multiple viewable windows 620 are spaced apart around the center of the base 64.
[0080] In this embodiment, when there are multiple viewing windows 620, the multiple viewing windows 620 are spaced apart around the center of the base 64, thereby increasing the visible area of the coil disk 3.
[0081] Optionally, if there is only one viewing window 620, the viewing window 620 can be positioned in the center of the coil 3. Optionally, the bottom wall of the support base 6 can be completely removed to form a large through hole 640, so that the viewing window 620 can be embedded in the bottom of the support base 6, thereby increasing the area of the viewing window 620.
[0082] like Figure 2 and Figure 5 As shown, in some embodiments, optionally, a display section 34 is provided on the side of the coil disk 3 facing the light-transmitting structure 62, and the display section 34 is disposed opposite to the light-transmitting structure 62.
[0083] In this embodiment, a display section 34 is provided on the side of the coil disk 3 facing the light-transmitting structure 62. The display section 34 is disposed opposite to the light-transmitting structure 62, thereby making the coil disk 3 more visible under the viewing window 620.
[0084] Optionally, the display unit 34 may include coatings of different colors or coatings forming different graphics or text, or the display unit 34 may be a light display unit so that the display unit 34 can emit light so that the user can observe it.
[0085] In some embodiments, the drive assembly 4 can optionally drive the coil 3 to move up and down between a first position close to the heating container 2 and a second position far from the heating container 2.
[0086] In this embodiment, the driving component 4 drives the coil 3 to move up and down relative to the heating container 2 between a first position and a second position. This allows the magnetic field generated by the coil 3 to gradually approach or move away from the heating container 2, changing the distance between the coil 3 and the heating container 2. Consequently, this alters the coupled magnetic field between the coil 3 and the heating container 2, enabling stepless adjustment of the heating power of the cooking appliance. Furthermore, the method of adjusting the distance between the coil 3 and the heating container 2 by driving the coil 3 to move up and down is relatively simple, reducing the manufacturing difficulty of the driving component 4.
[0087] In some embodiments, the distance between the first position and the second position may be greater than 0 mm and less than or equal to 100 mm.
[0088] In this embodiment, the lifting range of the coil 3 is set to be greater than 0 mm and less than or equal to 100 mm, which can reduce the impact of the lifting of the coil 3 on the overall height of the cooking appliance, and also ensure the adjustable range of heating power.
[0089] In practical applications, the distance between the first position and the second position is any value among 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm, and 100mm, or any value between any two values.
[0090] Optionally, the drive assembly 4 is used to drive the coil disk 3 to reciprocate between the first position and the second position, or to drive the coil disk 3 to move to any position between the first position and the second position.
[0091] like Figure 5 As shown, in some embodiments, optionally, the support base 6 is provided with a first limiting part 60, and the coil disk 3 is provided with a second limiting part 32. The first limiting part 60 and the second limiting part 32 are slidably connected along the lifting direction of the coil disk 3.
[0092] In this embodiment, a first limiting part 60 is provided on the support base 6, and a second limiting part 32 is provided on the coil disk 3. The first limiting part 60 and the second limiting part 32 are slidably connected, which realizes the lifting and lowering of the coil disk 3 along a predetermined trajectory, which can prevent the radial position of the coil disk 3 from shifting and ensure the reliability of the movement position of the coil disk 3.
[0093] Optionally, the coil 3 can be raised and lowered along the vertical direction of the cooking appliance.
[0094] Optionally, one of the first limiting part 60 and the second limiting part 32 is an opening, and the other is a column, with the column passing through the opening. Specifically, the opening is located in the middle of the coil 3.
[0095] Optionally, the coil disk 3 is provided with multiple sliders on its periphery, and the support base 6 is provided with multiple grooves. The sliders slide in the grooves to limit the circumferential movement of the coil disk 3 and prevent the coil disk 3 from rotating relative to the support base 6.
[0096] like Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, optionally, the drive assembly 4 includes: a drive part 40; a motion part 42 connected to the drive part 40; the motion part 42 is provided with a first mating part 420, and the coil disk 3 is provided with a second mating part 30. The first mating part 420 contacts the second mating part 30, and the drive part 40 can drive the motion part 42 to rotate. The first mating part 420 rotates relative to the second mating part 30 to make the coil disk 3 rise and fall.
[0097] In this embodiment, the drive assembly 4 includes a drive unit 40 and a moving unit 42. The moving unit 42 has a first engaging part 420, and the coil 3 has a second engaging part 30. The first engaging part 420 and the second engaging part 30 are in contact. The drive unit 40 can drive the moving unit 42 to rotate. During the rotation of the moving unit 42, the first engaging part 420 rotates relative to the second engaging part 30. With the cooperation of the first engaging part 420 and the second engaging part 30, the coil 3 with the second engaging part 30 rises and falls, thereby changing the distance between the coil 3 and the heating container 2. This adjusts the coupling between the coil 3 and the heating container 2 during cooking, thus adjusting the heating power of the cooking appliance. In other words, this application converts the rotation of the moving unit 42 into the rising and falling of the coil 3, reducing the overall space occupied by the drive assembly 4 in the height direction of the cooking appliance.
[0098] Optionally, the lifting of the coil 3 can be a linear movement along the vertical direction, or a swaying lifting, a spiral lifting, or a lifting at a certain angle to the vertical direction.
[0099] Optionally, the vertical direction is the direction of the rotation axis of the moving part 42.
[0100] like Figure 7 As shown, in some embodiments, optionally, one of the first mating portion 420 and the second mating portion 30 includes a first protrusion 4200 and a first recess 4202, the first protrusion 4200 and the first recess 4202 are alternately arranged along the rotation direction of the moving portion 42, and the other of the first mating portion 420 and the second mating portion 30 can alternately engage with the first protrusion 4200 and the first recess 4202 to make the coil disk 3 rise and fall between the first position and the second position.
[0101] In this embodiment, the first mating part 420 and the second mating part 30 achieve the switching from rotation to linear movement through a concave-convex structure. One of the first mating parts 420 and 30 includes a first protrusion 4200 and a first concave part 4202. As the first mating part 420 rotates with the moving part 42, the other of the first mating part 420 and the other of the second mating part 30 alternately passes through the first protrusion 4200 and the first concave part 4202, thereby realizing the reciprocating lifting and lowering of the coil 3. When the other of the first mating part 420 and the other of the second mating part 30 engages with the first protrusion 4200, the first mating part 420 and the other of the second mating part 30 together lift the coil 3, bringing it closer to the heating container 2. When the other of the first mating part 420 and the other of the second mating part 30 engages with the first concave part 4202, the coil 3 descends, moving it away from the heating container 2.
[0102] It is understandable that, along the axial direction of the moving part 42, the first protrusion 4200 protrudes toward the other of the first mating part 420 and the second mating part 30, and the first recess 4202 is recessed in a direction away from the other of the first mating part 420 and the second mating part 30.
[0103] In some embodiments, optionally, one of the first mating part 420 and the second mating part 30 includes an inclined surface structure, the inclined surface structure being inclined relative to the axis of rotation of the moving part 42, and the other of the first mating part 420 and the second mating part 30 includes a slider structure, the slider structure being able to slide along the inclined surface structure as the moving part 42 rotates, thereby driving the coil disk 3 to rise and fall.
[0104] like Figure 7 As shown, in some embodiments, optionally, the other of the first mating portion 420 and the second mating portion 30 further includes a second protrusion 300 and a second recess 302, and the second protrusion 300 and the second recess 302 are alternately arranged along the rotation direction of the moving portion 42.
[0105] In this embodiment, the other of the first mating part 420 and the second mating part 30 further includes a second protrusion 300 and a second recess 302. The second protrusion 300 and the second recess 302 are alternately arranged along the rotation direction of the moving part 42. Thus, the second protrusion 300 and the second recess 302 alternately cooperate with the first protrusion 4200 and the first recess 4202, which increases the lifting range of the coil 3, thereby increasing the adjustable range of the heating power of the cooking appliance and improving the stability of the drive between the coil 3 and the moving part 42.
[0106] It is understandable that, along the axial direction of the moving part 42, the second protrusion 300 protrudes towards the first protrusion 4200, and the second concave part 302 is recessed in the direction away from the first protrusion 4200.
[0107] Optionally, along the axial direction of the moving part 42, when the first protrusion 4200 contacts the second protrusion 300, the coil disk 3 is located in the first position; when the second concave part 302 contacts the first protrusion 4200 and the second protrusion 300 contacts the first concave part 4202, the coil disk 3 is located in the second position.
[0108] In some embodiments, optionally, the first protrusion 4200 and the first recess 4202 are connected sequentially along the rotation direction, or the first protrusion 4200 and the first recess 4202 are spaced apart along the rotation direction; and / or the second protrusion 300 and the second recess 302 are connected sequentially along the rotation direction, or the second protrusion 300 and the second recess 302 are spaced apart along the rotation direction; and / or the second mating part 30 is located in the middle of the coil disk 3, the coil on the coil disk 3 is located around the second mating part 30, or the second mating part 30 is arranged along the radial direction of the moving part 42 close to the side wall of the coil disk 3, and the second mating part 30 surrounds the coil on the coil disk 3.
[0109] In this embodiment, the first protrusion 4200 and the first recess 4202 are sequentially connected along the rotation direction of the moving part 42. This makes the movement of the coil 3 smoother during the rotation of the moving part 42 and allows the coil 3 to continuously rise and fall with the continuous rotation of the moving part 42. Consequently, the induced magnetic field of the heating container 2 continuously changes, increasing the adjustable range of heating power during cooking. Alternatively, the first protrusion 4200 and the first recess 4202 can be spaced apart along the rotation direction, making the rising and falling of the coil 3 non-continuous, achieving intermittent rising and falling of the coil 3. Correspondingly, the second protrusion 300 and the second recess 302 can also be sequentially connected or intermittently arranged. Optionally, the second mating part 30 can be located in the middle of the coil 3 to increase the winding area of the coil; the second mating part 30 can also be located radially outward of the coil 3 to increase the reliability and stability of the transmission.
[0110] Optionally, the rotation direction of the moving part 42 can be Figure 7 The direction indicated by the middle arrow can also be the opposite direction.
[0111] like Figure 6 As shown, in some embodiments, optionally, the driving part 40 includes a driving motor 400, and the moving part 42 includes a first gear 422, which is located on the side of the coil disk 3 away from the support base 6. A first mating part 420 is disposed on the first gear 422, wherein the driving motor 400 is disposed in the middle of the first gear 422 to drive the first gear 422 to rotate. Alternatively, the moving part 42 may also include a second gear 424, which is connected to the driving motor 400, and the first gear 422 meshes with the second gear 424.
[0112] In this embodiment, the drive unit 40 includes a drive motor 400, and the motion unit 42 includes a first gear 422. The drive motor 400 is connected to the middle of the first gear 422, so that the drive motor 400 directly drives the first gear 422 to rotate, reducing the number of transmission components. Alternatively, the motion unit 42 also includes a second gear 424. The drive motor 400 is connected to the second gear 424, and the first gear 422 meshes with the second gear 424. The drive motor 400 drives the first gear 422 to rotate through the second gear 424. In this way, the drive motor 400 can be placed around the first gear 422, reducing the overall height of the cooking appliance. The cooking appliance proposed in this application realizes the lifting and lowering of the coil 3 through the rotation of the drive motor 400 and the gear structure, making the lifting and lowering of the coil 3 more stable and reliable. At the same time, converting rotation into lifting motion can also reduce the space occupied by the drive component 4 in the height direction.
[0113] Optionally, the cooking appliance also includes a support 5, which is disposed inside the housing 1. The first gear 422 is supported on the side opposite to the coil 3 and is able to rotate relative to the support 5.
[0114] Optionally, along the axis of rotation of the first gear 422, the support member 5 is provided with multiple support ribs on the side facing the first gear 422. The support member 5 contacts the first gear 422 through the support ribs, which reduces the contact area between the support member 5 and the first gear 422. As a result, when the first gear 422 moves relative to the support member 5, the wear on the first gear 422 is reduced, as well as the frictional resistance and frictional noise of the rotation of the first gear 422 are also reduced.
[0115] In some embodiments, optionally, the drive unit 40 includes a hydraulic pump, the motion unit 42 includes a hydraulic cylinder, the hydraulic cylinder is provided with a first support rod, the coil disk 3 is provided on the first support rod, and the hydraulic pump drives the first support rod to rise and fall to drive the coil disk 3 to rise and fall; and / or the drive unit 40 includes a pneumatic pump, the motion unit 42 includes a sealed cavity, a second support rod is provided on one side of the sealed cavity, the coil disk 3 is provided on the second support rod, and the pneumatic pump drives the second support rod to rise and fall to drive the coil disk 3 to rise and fall; and / or the drive unit 40 includes a first magnetic element, the motion unit 42 includes a second magnetic element, at least one of the first magnetic element and the second magnetic element is an electromagnet, the second magnetic element is connected to the coil disk 3, and when the electromagnet is energized, the first magnetic element and the second magnetic element attract or repel each other, causing the second magnetic element to move to push the coil disk 3 to rise and fall.
[0116] In this embodiment, the drive unit 40 can also directly drive the moving unit 42 to rise and fall, thereby raising and lowering the coil 3. For example, the drive unit 40 includes a hydraulic pump, and the moving unit 42 includes a hydraulic cylinder. The hydraulic cylinder is equipped with a first support rod. When the hydraulic pump operates, it drives the hydraulic cylinder to extend and retract, thereby causing the first support rod to raise and lower the coil 3. This makes the distance between the coil 3 and the heating container 2 adjustable, and thus the heating power adjustable. Alternatively, the drive unit 40 includes a pneumatic pump and a sealed cavity. The pneumatic pump drives the sealed cavity to expand or shrink, thereby causing the second support rod to raise and lower the coil 3. Or, the drive unit 40 includes a first magnetic element, and the moving unit 42 includes a second magnetic element. At least one of the first and second magnetic elements is an electromagnet. When the electromagnet is energized, the first and second magnetic elements attract or repel each other, thereby causing the second magnetic element to move. That is, the second magnetic element drives the coil 3 to rise and fall, thereby adjusting the distance between the coil 3 and the heating container 2, and thus adjusting the heating power.
[0117] In some embodiments, the cooking appliance may optionally include a magnetic shielding cover, which is disposed on the outside of the drive unit 40 to shield the drive unit 40 from magnetic interference.
[0118] In this embodiment, since the drive unit 40 contains a metal material, it is easily heated in a magnetic field. Therefore, the drive unit 40 is covered with a magnetic shield to isolate the magnetic field generated by the coil on the coil disk 3, thereby avoiding the situation where the magnetic field generated by the coil affects the overheating of the drive unit 40 and affects its performance.
[0119] like Figure 5 As shown, in some embodiments, the cooking appliance may optionally include a rolling element 8 disposed in at least one of the first mating portion 420 and the second mating portion 30, the first mating portion 420 and the second mating portion 30 being in contact through the rolling element 8.
[0120] In this embodiment, the cooking appliance also includes a rolling element 8. The first mating part 420 and the second mating part 30 contact each other through the rolling element 8, so that the sliding friction between the first mating part 420 and the second mating part 30 is converted into rolling friction, thereby reducing the frictional resistance between the first mating part 420 and the second mating part 30.
[0121] like Figure 7 As shown, in some embodiments, optionally, one of the first mating part 420 and the second mating part 30 is provided with a groove 4204, a portion of the rolling element 8 is embedded in the groove 4204 and can roll in the groove 4204, and another portion protrudes out of the groove 4204 and contacts the other of the first mating part 420 and the second mating part 30.
[0122] In this embodiment, one of the first mating part 420 and the second mating part 30 is provided with a groove 4204, a part of the rolling element 8 is disposed in the groove 4204, and another part of the rolling element 8 protrudes out of the groove 4204 and contacts the other of the first mating part 420 and the second mating part 30, thereby improving the connection strength between the rolling element 8 and the first mating part 420 or the second mating part 30 and preventing the rolling element 8 from falling off.
[0123] In some embodiments, the rolling element 8 may optionally include any one of a metal element, a silicone element, or a rubber element.
[0124] In this embodiment, the rolling element 8 can be a metal part to increase its strength, reduce its wear, and extend the lifespan of the cooking appliance. The rolling element 8 can also be a silicone or rubber part, which has wear resistance and can further increase its lifespan.
[0125] like Figure 5 and Figure 6 As shown, in some embodiments, the cooking appliance may optionally include at least one elastic element 7, which is disposed between the support base 6 and the coil 3, and the elastic element 7 is in a compressed state.
[0126] In this embodiment, under the action of the elastic element 7, the second mating portion 30 on the coil disk 3 is made to fit with the first mating portion 420 of the moving portion 42, ensuring the stability and reliability of the drive assembly 4 in driving the coil disk 3. Furthermore, the elastic element 7 is disposed between the support base 6 and the coil disk 3, which also limits the maximum stroke of the coil disk 3 to prevent damage to the support base 6, coil disk 3, or other components caused by abnormal movement of the coil disk 3 in the event of a problem with the drive assembly 4.
[0127] It is understandable that the elastic element 7 has a maximum compression amount, which in turn makes the elastic element 7 have a minimum size under the maximum compression amount, so that a certain distance can be maintained between the coil disk 3 and the support seat 6 to avoid the two from colliding or being squeezed and damaged.
[0128] Optionally, the two ends of the elastic element 7 are fixed to the outer bottom wall of the coil disk 3 and the support base 6 respectively, or the two ends of the elastic element 7 are in contact with the outer bottom wall of the coil disk 3 and the support base 6 respectively.
[0129] In some embodiments, optionally, a coil is wound around the outer wall of the support 6, and the coil on the support 6 can surround the heating container 2. When the coil on the support 6 is energized, it can generate a magnetic field to heat the heating container 2.
[0130] In this embodiment, a coil is wound around the outer wall of the support base 6. The coil on the support base 6 surrounds the heating container 2. When the coil on the support base 6 is energized, the heating container 2 can be heated. That is, both the coil on the coil disk 3 and the coil on the support base 6 can heat the heating container 2. Optionally, the coil on the coil disk 3 and the coil on the support base 6 can heat the heating container 2 simultaneously, or the coil on the coil disk 3 and the coil on the support base 6 can heat the heating container 2 separately.
[0131] In some embodiments, the cooking appliance may optionally include a control device connected to the drive assembly 4 for controlling the operation of the drive assembly 4 to adjust the heating power of the cooking appliance by adjusting the distance between the coil 3 and the heating container 2.
[0132] In this embodiment, the cooking appliance also includes a control device connected to the drive assembly 4 for controlling the operation of the drive assembly 4. The control device controls the drive assembly 4 to drive the coil 3 to move, thereby adjusting the distance between the coil 3 and the heating container 2, adjusting the coupling between the coil 3 and the heating container 2, and thus adjusting the heating power of the cooking appliance.
[0133] Optionally, such as Figure 8 As shown, a detection component 9 is provided on the support base 6, the housing 1, or the support member 5. The detection component 9 is used to determine the position of the coil 3 based on the magnetic field of the coil 3. The control device is connected to the detection component 9, and then the control device controls the drive component 4 to work based on the information fed back by the detection component 9, so as to realize the adjustment of the position of the coil 3 and the adjustment of the heating power of the cooking appliance.
[0134] Optionally, the detection component 9 includes position detection mechanisms such as microswitches, reed switches, and optical gratings.
[0135] Optionally, cooking appliances include electromagnetic heating products, specifically including rice cookers, electric pressure cookers, or electric slow cookers.
[0136] Optionally, in some embodiments, this application proposes a visible and height-adjustable coil plate 3 to facilitate the detection and monitoring of whether the system is operating normally, and to allow users to experience the fun of cooking with the coil plate rising and falling. Specifically, a transparent window (e.g., viewing window 620) is designed on the non-moving part 42—the large coil plate 3 (e.g., support base 6)—allowing a view of the rising and rotating plate (e.g., coil plate 3). The transparent window is generally made of high-temperature resistant plastic or glass and can be fixed using adhesive, heat fusion, screws, clips, etc.
[0137] Optionally, patterns, colors, stripes, or other treatments can be applied to the visible surface of the lifting plate, or related parts can be added to make the lifting plate more visually noticeable when it rotates and rises.
[0138] Optionally, the large coil 3 can also be made entirely transparent to make the lower lifting plate visible.
