Description

Technical Field

[0001] This application relates to the field of cooking utensil technology, and more specifically to a cooking utensil. Background Technology

[0002] In existing cooking appliances, heat is easily lost from the bottom of the pot when heating, resulting in insufficient thermal efficiency. Therefore, a cooking appliance is needed to at least partially solve the above problems. Utility Model Content

[0003] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0004] To at least partially solve the above problems, this application provides a cooking appliance, the cooking appliance comprising: The pot body has a bottom heating assembly at its bottom, which includes a bottom heating component for achieving the heating function. A pot inner liner is disposed within the cooker body, and the interior of the pot inner liner forms a cooking cavity for holding food. The pot inner liner wall includes a bottom heating area, and in the vertical projection of the cooking appliance, the outer peripheral edge of the bottom heating area coincides with the outer peripheral edge of the bottom heating element; and The barrier mechanism is ring-shaped and includes two oppositely arranged sides. One side of the barrier mechanism contacts the pot body, and the other side contacts the outer surface of the inner pot on the outer periphery of the bottom heating area.

[0005] According to this application, the heat-concentrating mechanism helps to concentrate heat at the bottom and prevent it from leaking to the sides, thus improving the thermal efficiency of heating the bottom of the pot. When heat is concentrated at the bottom of the pot, there is a significant temperature difference between the bottom and the sides, resulting in a larger temperature difference between the top and bottom of the food. This promotes convection, encourages the food to tumble, and improves cooking quality. Furthermore, since the food occupies the space at the bottom of the pot first, concentrating energy there also ensures that energy is fully utilized and avoids waste.

[0006] Optionally, the barrier mechanism includes a plurality of ribs, the ribs being constructed in an annular shape and spaced apart along the radial and / or axial directions.

[0007] According to this application, multiple ribs provide better thermal insulation.

[0008] Optionally, the barrier mechanism is configured as a sealing ring, which surrounds the outer periphery of the inner pot. The outer periphery of the sealing ring is used to contact the pot body, and the inner periphery of the sealing ring is used to contact the outer surface of the inner pot on the outer periphery of the bottom heating area.

[0009] According to this application, the barrier mechanism is constructed as a sealing ring, which is inexpensive and has good heat insulation effect.

[0010] Optionally, the sealing ring includes a connecting part, a supporting part, and a sealing part connected in sequence. The connecting part is located on the outer periphery of the sealing ring and is used to connect to the pot body. The supporting part is used to contact the pot body. The sealing part extends upward from the supporting part so that when the inner pot is placed in the pot body, the inner pot squeezes the sealing part.

[0011] According to this application, the upwardly extending sealing portion of the sealing ring can contact the outer surface of the inner pot. Thus, the sealing ring can tightly block the transfer of heat from the bottom heating element to the sides. The support portion is used to contact the pot body, so that the pot body can support the sealing ring.

[0012] Optionally, the sealing part includes a first sealing part and a second sealing part connected in sequence. The first sealing part extends upward and one end is connected to the support part. An angle is formed between the first sealing part and the support part. The other end of the first sealing part is connected to the second sealing part and an angle is formed between them. The connection between the first sealing part and the second sealing part is used to abut against the inner pot, or the second sealing part is used to abut against the inner pot.

[0013] According to this application, the sealing part is constructed in an upwardly extending and bent form, which facilitates the contact of the sealing part with the outer surface of the pot.

[0014] Optionally, the sealing ring further includes a folded-back portion connected to one end of the second sealing portion, the folded-back portion extending downward from the second sealing portion.

[0015] According to this application, the fold-back portion extends downward so as to contact the support portion, such that the support portion, the sealing portion, and the fold-back portion enclose a cavity, which can further help prevent the bottom heating assembly from transferring heat to the side.

[0016] Optionally, the pot body includes a side heating assembly, and the side heating assembly and the bottom heating assembly clamp the connecting portion.

[0017] According to this application, the sealing ring can also block the heat from the side heat source from being transferred to the bottom, so that the side and bottom of the pot can be independently controlled in temperature.

[0018] Optionally, the barrier mechanism includes an annular protrusion structure disposed on the pot body.

[0019] According to this application, the barrier mechanism can be formed in the pot body.

[0020] Optionally, the bottom heating assembly further includes a bottom support member that supports the bottom heating assembly. The bottom support member is located at the bottom of the pot body, and the annular protrusion is disposed on the top of the bottom support member. The pot body includes a side heating assembly, and the side heating assembly and the bottom heating assembly clamp the connecting part.

[0021] According to this application, the barrier mechanism can be formed in the bottom support component of the bottom heating assembly of the pot body.

[0022] Optionally, the pot body includes a heat-insulating ring, which surrounds the outer periphery of the side of the inner pot, and the bottom of the heat-insulating ring is provided with the barrier mechanism extending toward one side of the inner pot. Alternatively, the bottom heating assembly may further include a bottom support component that supports the bottom heating assembly and is located at the bottom of the pot body, with the top of the bottom support component being disposed on top of the bottom support component.

[0023] According to this application, the location of the barrier mechanism can be flexibly set.

[0024] Optionally, the outer surface of the inner pot is provided with a radially outwardly extending protrusion structure on the outer periphery of the bottom heating area, the radially outer side of the protrusion structure is used to contact the pot body, and the protrusion structure forms the barrier mechanism.

[0025] According to this application, the barrier mechanism can be formed on the outer surface of the pot.

[0026] Optionally, the pot body includes a receiving cavity for accommodating the inner pot. When the inner pot is placed in the receiving cavity, the barrier mechanism abuts against and supports the inner pot, so that there is a gap between the flange of the inner pot's rim and the middle plate of the pot body.

[0027] According to this application, when the inner pot is placed in the pot body, the barrier mechanism supports the inner pot, thereby blocking the gap between the inner pot and the pot body, so that the heat at the bottom is not transferred to the side.

[0028] Optionally, the gap is less than or equal to 10 mm.

[0029] According to this application, when the inner pot is placed in the pot body, the inner pot will not protrude too much from the pot body, thus allowing it to make good contact with the sealing ring of the lid and the pot opening.

[0030] Optionally, the barrier mechanism comprises a high thermal resistance material; and / or The barrier mechanism includes a reflective material or has a reflective coating.

[0031] According to this application, high thermal resistance materials, reflective materials, and reflective coatings all help to block heat transfer between the bottom and the sides.

[0032] Optionally, the outer surface of the pot has a pot connecting portion for connection with the barrier mechanism. The pot connecting portion is located on the outer periphery of the bottom heating area. Along the extension direction of the generatrix of the pot wall, the distance between the pot connecting portion and the outer periphery of the bottom heating area is 10mm to 50mm.

[0033] According to this application, the barrier mechanism maintains a suitable distance from the heat source, which can both concentrate heat and prevent high-temperature aging and deformation to a certain extent. Attached Figure Description

However, it will be apparent to those skilled in the art that this application can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described to avoid confusion with this application.

[0037] To fully understand this application, a detailed description will be provided in the following description.

[0041] Unless otherwise stated, the numerical ranges in this document include not only the entire range within its two endpoints, but also the subranges contained therein.

[0042] This application provides a cooking utensil.

[0043] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings.

[0044] like Figure 1 As shown, in a specific embodiment, the cooking appliance 100 according to this application may include a pot body 12 and a lid 11. Typically, the pot body 12 is used to heat the inner pot 20, which is a cooking container for holding food. The internal space of the inner pot 20 is a cooking cavity. The pot body 12 may have a cylindrical (or other shaped) receiving cavity 14, from which the inner pot 20 can be freely placed or removed for easy cleaning. The inner pot 20 is made of metal and constructed as a rotating body with an opening and an inner cavity formed by the pot wall; that is, the inner pot 20 is constructed as a rotating body shape with an axis PA extending in the vertical direction as its axis (the inner pot wall is formed by rotating a fixed-shape generatrix around the axis PA by 360 degrees). The inner surface of the inner pot 20 has no coating, such as a non-stick coating. The capacity of the inner pot 20 is typically less than 6L; for example, the capacity of the inner pot 20 may be 2L or 4L, etc. The lid 11 is pivotally connected to the pot body 12 via a pivot shaft for closing the pot body 12.

[0045] The pot body 12 has a heating element for cooking. The heating element is positioned around the periphery of the inner pot 20 for heating the inner pot 20. The heating element is electrically connected to a control device (not shown) for heating the inner pot 20 under the control of the control device, thereby achieving the cooking function. The control device is configured, for example, as a MCU chip. The control device has built-in control program software.

[0046] The cooking appliance 100 also includes a temperature sensing device for sensing the cooking heating temperature. The temperature sensing device is electrically connected to a control device, allowing the control device to obtain cooking heating temperature information and control the heating components to operate based on this information. The temperature sensing device may include, for example, at least a top temperature sensor 18 and a bottom temperature sensor 19. The top temperature sensor 18, for example, is disposed in the lid 11 and senses the cooking heating temperature at the top of the cooking cavity. The bottom temperature sensor 19, for example, is disposed in the pot body 12 and contacts the bottom of the inner pot 20 to sense the cooking heating temperature at the bottom of the cooking container. The temperature sensing device may also include temperature sensors disposed in other locations.

[0047] Understandably, the cooking appliance 100 is controlled by a control device.

[0048] The inner pot 20 has an inner pot wall 91 including a bottom 21 (bottom wall) and a side portion 24 (side wall) located above the bottom 21. The heating assembly includes, for example, a bottom heating assembly 41. The bottom heating assembly 41 is located at the bottom of the pot body 12, corresponding to the bottom 21 of the inner pot, below the inner pot 20, and is used to heat the bottom 21 of the inner pot.

[0049] like Figure 2 As shown, the bottom heating assembly 41 includes a bottom support member 45 and a bottom heating member 46. The bottom support member 45 is disposed at the bottom of the pot body 12. The bottom heating member 46 is disposed on the bottom support member 45 and is used to realize the heating function. For example, the bottom heating member 46 is also constructed as an electromagnetic heating coil 54, which is wound around the lower surface of the bottom support member 45, thereby the bottom heating assembly 41 is also an electromagnetic heating device.

[0050] The cooking appliance 100 includes a heat-insulating ring 63. The heat-insulating ring 63 is, for example, constructed in a circular shape and used to surround the outer periphery of the side portion 24 of the inner pot. The heat-insulating ring 63 is, for example, constructed of plastic and provides heat retention. A bottom support member 45 supports the heat-insulating ring 63. Thus, the receiving cavity 14 can be understood as being enclosed by the side heat-insulating ring 63 and the bottom heating element 41. For example, the heat-insulating ring 63 forms the side wall of the receiving cavity 14, and the bottom support member 45 forms the bottom wall of the receiving cavity 14.

[0051] Typically, the inner pot 20 is constructed in a rotating shape, and to accommodate this shape, the bottom heating element 46 is usually arranged in a disc or ring. For example... Figure 3As shown, the inner pot 20 and the bottom heating element 46 are substantially coaxial. The bottom 21 of the inner pot wall 91 includes a bottom heating area 21A. In the vertical projection of the cooking appliance 100, the outer peripheral edge of the bottom heating area 21A coincides with the outer peripheral edge of the bottom heating element 46. That is, the outer diameter DO1 of the bottom heating element 46 defines the size of the bottom heating area 21A, and the bottom heating area 21A and the bottom heating element 46 have the same outer diameter DO1. The bottom heating area 21A is the area that most directly receives the heat source. For example, the outer peripheral edge of the bottom heating area 21A is point A in the figure.

[0052] To concentrate the energy of the bottom heat source on the bottom 21 of the inner pot, the cooking appliance 100 also includes a barrier mechanism 51. For example, the barrier mechanism 51 is annular, with two oppositely arranged sides. One side contacts the pot body 12, and the other side contacts the outer surface of the inner pot 20 on the outer periphery of the bottom heated area, thus separating the inner pot 20 from the pot body 12 through a gap 13. Understandably, the gap 13 is part of the receiving cavity 14. Therefore, the heat from the bottom heating element 41 is blocked by the barrier mechanism 51, making it difficult for the heat source to flow to the sides, thus concentrating the heat in the bottom area. Since the food first occupies the space at the bottom of the pot, concentrating the energy at the bottom allows for full utilization of energy, avoids waste, and improves heating efficiency. When the heat is concentrated at the bottom of the pot, there is a significant temperature difference between the bottom and sides, resulting in a larger temperature difference between the top and bottom of the food, which is conducive to convection, promotes tumbling of the food, and improves cooking quality.

[0053] To ensure effective heat insulation, the barrier mechanism 51 is typically made of a high thermal resistance material, such as plastic, silicone, or resin. These materials are prone to high-temperature aging (and some may also experience high-temperature deformation), therefore, the barrier mechanism 51 cannot be too close to the bottom heat source. Simultaneously, to effectively concentrate heat, the barrier mechanism 51 cannot be too far from the bottom heat source. At the barrier mechanism 51, the outer surface of the pot liner 20 has a pot liner connecting portion 104 for connection to the barrier mechanism 51, located on the outer periphery of the bottom heated area 21A. Preferably, along the extension direction DG of the generatrix of the pot liner wall 91, the distance HID between the pot liner connecting portion 104 and the outer periphery of the bottom heated area 21A is 10 mm to 50 mm.

[0054] Optionally, such as Figure 1 and 4As shown, the blocking mechanism 51 can be configured as a sealing ring 16. The sealing ring 16 has two opposing sides, one side for contacting the pot body 12 and the other side for contacting the outer surface of the inner pot 20, so that the gap 13 is blocked in the middle. For example, the sealing ring 16 is used to surround the outer periphery of the inner pot 20, with the outer periphery of the sealing ring 16 contacting the pot body 12 and the inner periphery of the sealing ring 16 contacting the inner pot 20, so that the gap 13 is blocked in the middle. Figure 4 As shown, optionally, the outer periphery of the sealing ring 16 includes a sealing ring mounting groove 16A, which is used to connect with the pot body 12. For example, the heat preservation ring 63 is inserted into the sealing ring mounting groove 16A.

[0055] like Figure 5 As shown, optionally, the inner circumferential side of the sealing ring 16 includes a bent structure 16B, at least a portion of which is configured to bend from inward and downward to outward and upward. Thus, when the inner pot 20 is placed in the pot body 12, the inward and downward extending portion of the bent structure 16B can contact the bottom heating assembly 41 (specifically, the bottom support member 45), and the outward and upward extending portion of the bent structure 16B can contact the outer surface of the inner pot 20. Therefore, the bent structure 16B can tightly seal the gap 13.

[0056] For example, the sealing ring 16 includes a connecting portion 16H, a support portion 16C, and a sealing portion 16J connected in sequence. The connecting portion 16H is located on the outer periphery of the sealing ring 16 and is used to connect with the pot body 12; for example, a sealing ring mounting groove 16A is provided in the connecting portion 16H. The support portion 16C extends downward from the connecting portion 16H, for example, extending inward and downward, to contact the pot body 12. The sealing portion 16J extends upward from the support portion 16C so that the pot body 20 presses against the sealing portion 16J when it is placed in the pot body. Further, the sealing portion 16J includes a first sealing portion 16D and a second sealing portion 16E connected in sequence. One end of the first sealing portion 16D is connected to the support portion 16C and extends upward (e.g., inward and upward) from the support portion. An angle (not zero) is formed between the first sealing portion 16D and the support portion 16C. The other end of the first sealing portion 16D is connected to the second sealing portion 16E. An angle (not zero) is formed between the first sealing portion 16D and the second sealing portion 16E. For example, the second sealing part 16E extends outward and upward from the first sealing part 16D. The connection between the first sealing part 16D and the second sealing part 16E is used to abut against the inner pot 20, or the second sealing part 16E is used to abut against the inner pot 20.

[0057] The bent structure 16B includes a support portion 16C, a first sealing portion 16D, and a second sealing portion 16E. The support portion 16C is used to contact the upper surface of the bottom support member 45 or other pot body components, thereby supporting the sealing ring 16. The sealing portion 16J protrudes and bends (bends) towards the inner pot 20, making it easier to contact the outer surface of the inner pot 20 and improving the sealing performance.

[0058] Furthermore, such as Figure 6 As shown, the bending structure 16B may further include a fold-back portion 16F. The fold-back portion 16F extends downward from the second sealing portion 16E, for example, bending outward and downward to approach the outer periphery of the sealing ring 16. Thus, the bending structure 16B is bent almost 360 degrees, forming a cavity 16G inside the bending structure 16B. For example, the fold-back portion 16F, the sealing portion 16J, and the support portion 16C surround the cavity 16G. The air inside the cavity 16G is a poor conductor of heat, helping to block heat transfer between the bottom and the sides.

[0059] In the illustrated embodiment, each of the support portion 16C, the first sealing portion 16D, the second sealing portion 16E, and the folding portion 16F extends in a straight line, with a bending angle of approximately 90 degrees at the points of connection between any two. However, the bending structure 16B can also be constructed as a curved bend.

[0060] Of course, the outer periphery of the sealing ring 16 can also be connected to the bottom heating assembly 41. For example, the sealing ring mounting groove 16A faces downwards, allowing the bottom support member 45 to be inserted therein. Alternatively, the sealing ring 16 can be generally constructed as a cylinder with its axial direction pointing up and down, with its lower side mounted on the bottom support member 45 and its upper side used to contact the outer surface of the pot liner 20. This is equivalent to the barrier mechanism 51 being located on top of the bottom support member 45. Alternatively, the connecting portion 16H of the sealing ring 16 can be sandwiched between the insulation ring 63 and the bottom support member 45.

[0061] The barrier mechanism 51 can also be constructed as an annular protrusion, for example, as a rigid annular protrusion of the pot body 12.

[0062] For example, in Figure 7 and Figure 8 In the illustrated embodiment, the barrier mechanism 51 of the cooking appliance 200 is provided in the heat-insulating ring 63. For example, the barrier mechanism 51 is formed at the bottom of the heat-insulating ring 63. For example, the bottom of the heat-insulating ring 63 is provided with an annular second protrusion 68 extending inward in the radial direction. The second protrusion 68 is used to contact the inner pot 20, thereby forming the barrier mechanism 51. The second protrusion 68 can be formed, for example, by constructing a flange or rib at the axial end of the heat-insulating ring 63. In this embodiment, the inner circumferential side of the annular second protrusion 68 contacts the inner pot 20, and the outer circumferential side is connected to (contacts) the pot body 12.

[0063] exist Figures 9 to 14 In the illustrated embodiment, the barrier mechanism 51 of the cooking appliances 300 and 400 is disposed on the top of the bottom heating assembly 41. For example, it is disposed on the top of the bottom support member 45. For example, the top of the bottom support member 45 is provided with an annular first protrusion structure 47, which contacts the inner pot 20, thereby forming the barrier mechanism 51. Figure 10 In the example, the inner circumferential side of the first protrusion structure 47 contacts the inner pot 20, and the outer circumferential side is connected to the pot body 12. Figure 12 In the example, the annular side (upper side) of the first protrusion structure 47 along the axial direction contacts the inner pot 20, and the other side (lower side) along the axial direction is connected to the pot body 12. Figure 14 In the example, the annular side (upper side) of the first protrusion structure 47B along the axial direction, which is also the inner circumference side, contacts the inner pot 20, and the other side (lower side) along the axial direction, which is also the outer circumference side, is connected to the pot body 12.

[0064] The barrier mechanism 51 may include a high thermal resistance material. For example, the barrier mechanism 51 may also include a high thermal resistance heat insulation sleeve 89 (e.g., a silicone sleeve, see [link]) disposed on the outer surface of the first protrusion structure 47 or the second protrusion structure 68. Figure 13 and Figure 14 This further prevents heat conduction between the bottom and sides. The barrier mechanism 51 may also include a reflective material or have a reflective coating, for example, a reflective material or reflective coating provided on the first protrusion structure 47 or the second protrusion structure 68, which can also prevent heat conduction between the bottom and sides.

[0065] exist Figures 15 to 17 In the illustrated embodiment, the outer surface of the inner pot 20 of the cooking appliance 500 is provided with a radially outwardly extending annular inner pot protrusion structure 25. The inner pot protrusion structure 25 is used to contact the pot body 12, for example, to contact the bottom support member 45, thereby forming a barrier mechanism 51. The inner pot protrusion structure 25 can also be used to contact the heat preservation ring 63. In this embodiment, the annular inner circumferential side of the inner pot protrusion structure 25 is connected to (contacts) the inner pot 20, and the outer circumferential side contacts the pot body 12. It is understood that the protrusion structure 25 is located on the outer circumferential side of the bottom heated area 21A.

[0066] The aforementioned first protrusion structure 47, second protrusion structure 68, and inner pot protrusion structure 25 can also be used in combination. Alternatively, a portion of the barrier mechanism 51 is formed on the outer surface of the inner pot 20, and another portion is formed on the pot body 12, with the two portions in contact. Alternatively, the barrier mechanism 51 includes multiple annular ribs, each rib having opposite sides, one side contacting the pot body 12 and the other side contacting the inner pot 20, i.e., each rib seals the gap 13. The opposite sides of the ribs are, for example, opposite sides along the axial and / or radial direction of the annulus. Multiple ribs provide better heat insulation. For example, Figure 14 In the example, the bottom heating assembly 41 is provided with two first protruding structures 47A and 47B, which is a specific example of heat insulation using multiple baffles. The multiple baffles can be all located in the pot body 12, all in the inner pot 20, or partially in the pot body 12 and partially in the inner pot 20. The multiple baffles can be spaced apart along the radial and / or axial direction of the annular barrier mechanism 51.

[0067] like Figure 3 As shown, the inner pot 20 has a radially outwardly extending flange 27 at its opening. (As shown...) Figure 7 , Figure 9 , Figure 11 and Figure 15 As shown, at the blocking mechanism 51, the pot contact portion 102 on the outer surface of the inner pot 20 contacts the pot body contact portion 101 of the pot body 12. A first distance D1 is formed in the vertical direction between the pot body contact portion 101 and the highest point of the periphery of the opening of the receiving cavity 14. A second distance D2 is formed in the vertical direction between the pot contact portion 102 and the lower surface of the pot rim flange 27 of the inner pot 20. D2 is greater than D1, so that when the inner pot 20 is placed in the pot body 12, it is supported by the blocking mechanism 51, rather than the flange 27, thus ensuring that the blocking mechanism 51 blocks the gap 13. Preferably, D2 is less than or equal to the sum of D1 and 10 mm, so that the inner pot 20 does not protrude too much from the pot body 12, and the pot rim of the inner pot 20 can make good contact with the pot rim sealing ring in the lid 11. In other words, when the inner pot 20 is placed in the receiving cavity 14, the blocking mechanism 51 abuts against and supports the inner pot 20, so that there is a gap in the vertical direction between the flange 27 of the inner pot 20 and the middle plate 12A of the pot body 12 (the middle plate 12A surrounds the receiving cavity 14). This gap is less than or equal to 10 mm.

[0068] Understandably, the inner pot contact portion 102 is an example of the inner pot connection portion 104 mentioned above.

[0069] In this application, the opposite radial sides of the annular barrier mechanism specifically refer to the inner and outer circumferential sides of the annulus.

[0070] In an embodiment not shown in this application, the pot body 12 further includes a side heating assembly corresponding to the side portion 24 of the inner pot. The side heating assembly surrounds the outer periphery of the side portion 24 of the inner pot and is primarily used for heating the side portion 24. A heat-insulating ring 23 is, for example, a component of the side heating assembly. The side heating element (e.g., a heating plate) of the side heating assembly, which performs the heating function, can be mounted on the outer periphery of the heat-insulating ring 23. Thus, the barrier mechanism 51, located between the side heating element and the bottom heating element, can also prevent heat from the side heat source from transferring to the bottom, making the bottom 21 and the side portion 24 of the inner pot areas independently heatable and temperature-controlled.

[0071] In such an embodiment, the barrier mechanism 51 may be, for example, a sealing ring 16, with the side heating assembly and the bottom heating assembly 41 clamping the connecting portion 16H of the sealing ring 16. The barrier mechanism 51 may also be the second protrusion structure 68, the first protrusion structure 47, and the inner pot protrusion structure 25 described above.
