Description

Technical Field

[0001] This utility model generally relates to the technical field of cooking appliances, and more specifically to a steam generating device and a cooking appliance. Background Technology

[0002] Steam cooking appliances such as steam rice cookers have independent steam generating devices and steam delivery channels. The steam generated by the steam generating device is delivered to the cooking chamber through the steam delivery channel to replenish the cooking chamber with steam, so as to maintain the moisture of the rice and make the rice have a better taste.

[0003] A steam generator consists of a heating element and a water container. The heating element heats the water in the container to produce steam. The heating element is generally a structure consisting of a heat-conducting component with an aluminum-cast or brazed heating tube, which is difficult to disassemble. When the heating element fails, the entire heating element needs to be replaced, resulting in high repair and replacement costs. Utility Model Content

[0004] 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.

[0005] To at least partially solve the above problems, the first aspect of this utility model provides a steam generating device for cooking appliances, the steam generating device comprising: Heating element; A housing, configured as a cover-like member with a top opening and including a bottom wall and side walls, the housing being located above the heating element; and A mounting base is located below the heating element and is fixedly connected to the bottom of the cover sidewall. The heating element is held between the fixing base and the bottom wall of the cover.

[0006] According to this solution, the heating element is clamped between the fixed base and the bottom wall of the cover. Thus, the heating element can be disassembled and assembled by removing and assembling the fixed base and the housing cover. Disassembly and assembly are convenient, and it is easy to replace the heating element individually without replacing the entire assembly composed of the heating element, thereby reducing the maintenance cost of the steam generator.

[0007] Optionally, the heating element includes a heat-conducting body segment with a heat-conducting plane. In the assembled state, the heat-conducting plane of the heat-conducting body segment is in contact with the bottom wall of the cover. According to this solution, the heat-conducting body segment of the heating element is attached to the bottom wall of the cover through the heat-conducting plane, so that the heating element and the receiving cover are in surface contact, thereby ensuring good heat transfer between the heating element and the receiving cover.

[0008] Optionally, the heating element includes a heating body segment and a connecting end. The heating body segment is clamped between the fixed base and the bottom wall of the cover, and the connecting end is connected to the heating body segment and located outside the fixed base. According to this design, the heating body segment, as the heat source of the heating element, is clamped between the fixed base and the bottom wall of the cover, while the connecting end, as the wiring portion of the heating element, is located away from the bottom wall of the cover. This ensures that the surface of the heating element in contact with the housing is the surface of the heating body segment, guaranteeing that almost all the heat generated by the heat source is transferred to the housing, thereby ensuring the heat transfer efficiency of the heating element to the housing and resulting in relatively uniform heating of the housing. Furthermore, the arrangement of the heating element facilitates assembly and connection operations on the production line, improving the assembly efficiency of the steam generator. The connecting end being outside the fixed base saves space inside the fixed base, facilitates the arrangement of the heating body segment, and makes connection to the wires easier.

[0009] Optionally, the mounting base has a mounting opening, and the connecting end extends beyond the mounting base through the mounting opening. According to this solution, the connecting end extends beyond the mounting base through the mounting opening, which allows the heating element to be positioned during assembly, making assembly easier; and restricts the position of the connecting end after assembly, thereby preventing displacement of the heating element.

[0010] Optionally, the heating element includes a heating body segment, and the mounting base includes a base bottom wall and a base side wall. The base side wall is connected to the base bottom wall and extends around the outer periphery of the base bottom wall. The heating body segment is located within a cavity formed by the base bottom wall and the base side wall. According to this solution, the heating body segment of the heating element is enclosed by the cavity formed by the mounting base and the base bottom wall. The mounting base can prevent the heat generated by the heating body segment from diffusing outwards, thereby reducing heat loss, improving the overall thermal efficiency of the steam generator, and preventing excessive temperature rise of adjacent components located outside the device.

[0011] Optionally, the heating element includes a heating body segment, the projection of which, on the projection along the central axis of the steam generator, lies within the projection of the fixing seat and / or the bottom wall of the enclosure. According to this design, the heating body segment is completely pressed against the fixing seat and the bottom wall of the enclosure, improving the fit between the heating body segment and the bottom wall, thereby ensuring good heat transfer between the heating element and the enclosure.

[0012] Optionally, the heating element includes a heating body section and a connecting end. On the projection along the central axis of the steam generator, the heating body section has an outer contour line, and the projection of the connecting end lies within the outer contour line. According to this solution, the connecting end of the heating element is compactly arranged with the heating body section, resulting in a more compact overall structure of the steam generator and improved space utilization.

[0013] Optionally, the outer contour line includes an arc shape. According to this solution, the heating element's main body section is mounted on the mounting base in an arc or spiral disc shape, with the projection of the connecting end located within the circle, making the heating element's structure more compact. The shape of the outer contour line corresponds to the external shape of the housing. According to this solution, the shape of the heating element's main body section matches the housing, which not only makes the heating of the housing by the heating element more uniform but also makes the overall structure of the steam generator more compact.

[0014] Optionally, the bottom wall of the cover has a recessed portion extending from the inside of the cover towards the outside. The steam generating device also includes fasteners, and the bottom wall of the recessed portion is connected to the fixing seat via the fasteners. According to this design, the interior of the recessed portion provides installation space for the fasteners, which are hidden below the plane of the bottom wall of the cover, making the overall structure of the device more compact. The fasteners provide pre-tightening force for the connection between the fixing seat and the housing cover, resulting in a tighter fit between the heating element and the bottom wall of the housing cover, leading to higher heat transfer efficiency.

[0015] Optionally, the steam generator further includes a sealing ring. The bottom wall of the recess has a mounting hole for the fastener to pass through, and the sealing ring is fitted around the edge of the mounting hole. According to this design, the sealing ring helps prevent moisture falling into the housing from seeping into the space where the heating element is located during use, thereby preventing short circuit damage to the heating element and avoiding malfunctions of the steam generator. The mounting base has a flanged hole protruding outwards from the bottom. The inner wall of the flanged hole is threaded, and the fastener is a threaded connector that passes through the mounting hole and is threaded into the flanged hole. According to this design, the flanged hole and its thread extend the connection length between the fastener and the mounting base, making the connection between the fastener and the mounting base more secure.

[0016] The second aspect of this utility model provides a cooking appliance, including a pot body, a lid, and a steam generating device according to the above description. The lid is closable and disposed on the pot body, forming a cooking cavity between the two. The lid is provided with a steam conveying channel, and the steam generating device is disposed on the pot body and communicates with the cooking cavity through the steam conveying channel.

[0017] According to this solution, the steam generated by the steam generator enters the cooking chamber through a steam delivery channel, thereby keeping the food inside the cooking chamber moist and improving its texture. The heating element of the steam generator can be easily disassembled and installed by removing and installing the mounting base and housing cover. This facilitates the replacement of the heating element alone, eliminating the need to replace the entire assembly consisting of the heating element, thus reducing the maintenance costs of the steam generator and the cooking appliance as a whole.

[0020] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.

[0021] To fully understand this application, a detailed description will be provided in the following description. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. Obviously, the implementation of the embodiments of this application is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other embodiments.

[0022] In this document, ordinal numbers such as "first" and "second" used in this invention are merely identifiers and do not have any other meaning, such as a specific order. Moreover, for example, the term "first component" does not imply the existence of "second component," and the term "second component" does not imply the existence of "first component."

[0023] In this document, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, and not to limit the absolute position of these related parts. In this document, terms such as "equal" and "same" are not strict mathematical and / or geometric limitations, and also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0024] 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.

[0025] This invention provides a cooking appliance capable of cooking food. The cooking appliance can be, for example, a rice cooker, an electric pressure cooker, or other cooking appliances, and in addition to cooking rice, it can also have various other functions such as cooking porridge.

[0026] Taking a rice cooker as an example, the cooking appliance includes a pot body 10 and a lid, as shown in the figure. Figure 1 The pot body 10 has a cylindrical storage section 11 and includes an inner pot 12. The inner pot 12 is typically made of metal and has a circular opening on its upper surface for holding food to be heated, such as rice or soup. The inner pot 12 is placed in the storage section 11. The pot body 10 also includes a heating device for heating the inner pot 12, thereby heating the inner pot 12 and cooking the food.

[0027] The lid has a shape that substantially corresponds to the pot body 10. The lid is closable on the pot body 10; specifically, it is pivotally connected to the pot body 10 via a pivot axis and can freely pivot about the pivot axis between a closed position and an open position relative to the pot body 10, facilitating the closing and opening of the pot body 10. When the lid is closed on the pot body 10, it covers the inner pot 12, forming a cooking cavity 13 between the lid and the inner pot 12. The lid typically also has a pot opening sealing ring, which can be made of, for example, rubber material, and is positioned between the lid and the inner pot 12 to seal the cooking cavity 13 when the lid is closed.

[0028] The pot body 2 mainly includes an outer shell 14, a main body 15 located on the upper side of the outer shell 14, and a base 16 located on the lower side of the outer shell 14. The lower end of the outer shell 14 can be connected to the outer periphery of the main body 15 by a suitable method such as snap-fit, fastener connection such as screws, or bonding. The lower end of the outer shell 14 can also be connected to the upper end of the base 16 by a suitable method such as snap-fit, fastener connection such as screws, or bonding. The main body 15 is also connected to the base 16 by fasteners such as screws.

[0029] To maintain the humidity of the food inside the cooking cavity 13, the pot body 10 also has a steam generator 20, which is located, for example, at the rear corner of the pot body 10. The lid has a steam delivery channel, through which the steam generator 20 communicates with the cooking cavity 13. The high-temperature steam generated by the steam generator 20 can be delivered to the cooking cavity 13 via the steam delivery channel, thereby maintaining the humidity of the food inside the cooking cavity 13 and giving the food a better texture.

[0030] The steam generating device 20 includes a water container 21 and a water container heating assembly 22. The water container 21 has a water container opening 23 for holding water that has been pre-placed through the opening 23. The water container heating assembly 22 is located below the water container 21 and is used to heat the water in the water container 41 to generate high-temperature steam. The water container heating assembly 22 is connected to the main body 15 of the pot body, for example, by snap-fit, fasteners such as screws, adhesive, or other suitable methods. The main body 15 of the pot body also has a through hole 17, through which the water container 21 is placed inside the water container heating assembly 22.

[0031] The following is in conjunction with the appendix Figures 2 to 7 The water container heating component 22 is described in detail.

[0032] Combination Figure 3 As shown, the water container heating assembly 22 of the steam generating device 20 includes a heating element 30, a housing 40, and a mounting base 50. The heating element 30 is used to generate heat. The housing 40 is constructed as a cover-like member with a top opening and has a housing cavity for housing the water container 21. Specifically, the housing 40 includes a bottom wall 41 and a side wall 42 connected to the bottom wall 41. The side wall 42 extends around the edge of the bottom wall 41 and closes, thereby forming a cover-like structure with a top opening. The bottom wall 41 supports the water container 21 when it is placed inside the housing 40.

[0033] The housing shroud 40 is located above the heating element 30, and the mounting base 50 is located below the heating element 30 and is fixedly connected to the bottom of the shroud sidewall 42. The heating element 30 is clamped between the mounting base 50 and the bottom wall 41 of the shroud, so that the heating element 30 is in close contact with the bottom wall 41 of the housing shroud 40, thus having good heat conduction efficiency. Furthermore, the heating element 30 can be disassembled and assembled by removing and installing the mounting base 50 and the housing shroud 40, which facilitates the replacement of the heating element 30 without having to replace the entire assembly composed of the heating element 30, thereby reducing the maintenance cost of the steam generator 20.

[0034] Heating element 30 is an electric heating element. Optionally, the electric heating element can be an electric heating tube. (See reference...) Figure 3 and Figure 4The heating element 30 includes a heating body section 31, which serves as the heat source of the heating element 30. When the heating element 30 is energized, the heating body section 31 generates heat, thereby heating the housing 40 and producing steam.

[0035] Reference Figure 3 The side of the heat-conducting main body section 31 near the bottom wall 41 of the cover has a heat-conducting plane 34. In the assembled state, the heat-conducting plane 34 of the heat-conducting main body section 31 is in contact with the bottom surface of the bottom wall 41 of the cover, so that the heating element 30 and the housing cover 40 are in surface contact, so that the heat on the heat-conducting main body section 31 can be fully transferred to the bottom wall 41 of the cover, thereby ensuring a good heat transfer effect between the heating element 30 and the housing cover 40.

[0036] Reference Figure 3 The mounting base 50 includes a side wall 51 and a bottom wall 52. The side wall 51 is connected to the bottom wall 52 and extends around the outer periphery of the bottom wall 52. The hot body section 31 can be located within the cavity formed by the bottom wall 52 and the side wall 51. This not only encloses the side of the hot body section 31, but also prevents the heat generated by the hot body section 31 from diffusing out of the mounting base 50, thereby reducing heat loss and improving the overall thermal efficiency of the steam generator 20. At the same time, it also prevents the temperature rise of adjacent components outside the steam generator 20 (such as the outer shell 14 of the pot body 10 and the downward extension plate of the pot body main body 15) from becoming too high.

[0037] Optionally, refer to Figure 3 The side wall 51 of the mounting base 50 corresponds to the side wall 42 of the cover. Specifically, along the axial direction D parallel to the steam generator 20, the projection of the cover side wall 42 at least partially overlaps with the projection of the side wall 51. The side wall 51 abuts against the bottom wall 41 of the cover and encloses at least a portion of the heating element 30 (specifically, the hot body section 31 of the heating element 30), thereby reducing heat loss from the heating element 30 and improving the thermal efficiency of the steam generator 20. It is understood that the heating element 30 is attached to the bottom surface of the bottom wall 41 of the cover, and the main heat generated by the heating element 30 is transferred to the bottom wall 41 of the cover.

[0038] The housing shroud 40 can be made of metal, especially iron, which has low manufacturing costs and good thermal conductivity and heat reflectivity. The bottom wall 41 of the shroud mainly serves to conduct heat, transferring heat to the water container 21. The side wall 42 of the shroud, in addition to heat conduction, also serves to reflect heat, transferring heat to the water container 21 through the side wall 42, and reflecting the heat from the water container 21, preventing heat loss. The mounting base 50 can be made of metal, such as iron, which has low manufacturing costs and good heat reflectivity. The mounting base 50 can reflect the heat from the heating element 30 towards the housing shroud 40. Iron materials include, for example, aluminized steel plates and galvanized steel plates, and the mounting base 50 can also be made of aluminum plates, stainless steel plates, etc.

[0039] Reference Figure 3 The heating element 30 also includes a connecting end 32 for connecting wires. The connecting end 32 is provided with terminals for easy connection of wires. The heating body section 31 is clamped between the fixing base 50 and the bottom wall 41 of the cover. The connecting end 32 is connected to the heating body section 31 and extends downward. Since the heating body section 31, as the main heat source of the heating element 30, is clamped between the fixing base 50 and the bottom wall 41, and the connecting end 32, as the wiring part of the heating element 30, is far away from the bottom wall 41, the surface of the heating element 30 that contacts the housing cover 40 is the surface of the heating body section 31. This ensures that almost all the heat generated by the heat source is transferred to the housing cover 40, thereby ensuring the heat transfer efficiency of the heating element 30 to the housing cover 40, and the housing cover 40 is heated relatively evenly. In addition, the arrangement of the heating element 30 facilitates the assembly and connection operation of the production line and helps to improve the assembly efficiency of the steam generator 20.

[0040] Reference Figure 2 and Figure 3 The mounting base 50 is provided with a mounting opening 53, and the connecting end 32 extends out of the mounting base 50 through the mounting opening 53, which saves the internal space of the mounting base 50, facilitates the setting of the hot body section 31, and makes it easy to connect with the wire.

[0041] Reference Figure 3 On the projection along the axial direction D of the steam generator 20, the projection of the hot body section 31 is located within the projection of the fixed seat 50 or the bottom wall 41 of the cover, or the projection of the hot body section 31 is located within the projection of the fixed seat 50 and the bottom wall 41 of the cover. This allows the hot body section 31 to be completely pressed by the fixed seat 50 and the bottom wall 41 of the cover, improving the fit between the hot body section 31 and the bottom wall 41 of the cover. This allows the heat generated by the heating element 30 to be fully transferred to the housing cover 40, thereby ensuring a good heat transfer effect between the heating element 30 and the housing cover 40.

[0042] Reference Figure 5On the projection along the axial direction D of the steam generator 20, the hot body section 31 has an outer contour line 33, and the projection of the connecting end 32 is located within the outer contour line 33, so that the connecting end 32 of the heating element 30 is arranged compactly with the hot body section 31, thereby making the structure of the steam generator 20 more compact and improving the overall space utilization of the steam generator 20. In addition, it also makes the heating element 30 more suitable for the installation of the regularly formed housing cover 40 and the fixing seat 50.

[0043] Optionally, the outer contour line 33 includes an arc shape, which can be adapted to the circular opening of the receiving cover 40 and the fixing base 50. This not only makes the heating element 30 heat the receiving cover 40 more evenly, but also makes the overall structure of the steam generating device 20 more compact. In addition, the outer contour line 33 can also be a graphic with a partially regular shape, such as a polygon or a polygon with rounded corners, all of which should be within the protection scope of this utility model.

[0044] Reference Figure 3 The shape of the outer contour line 33 corresponds to the external shape of the housing 40, and even the shape of the outer contour line 33 corresponds to the shape of the fixing seat 50. For example, in the illustrated embodiment, the outer contour line 33 is circular, the housing 40 is cylindrical, and the fixing seat 50 is a disc-like shape with a cavity. The internal structure of the steam generator 20 is more compact, the space utilization is higher, and the external shape of the steam generator 20 is more uniform.

[0045] Reference Figure 3 and Figure 4 The heating element 30 has a main heating section 31 spirally arranged around the axis AX of the steam generator 20. The two connecting ends 32 of the heating element 30 are respectively located at both ends of the main heating section 31 and extend downward through the seat opening 53 provided on the bottom wall 52 of the seat. The heating element 30 is connected to and energized from the outside of the fixed seat 50, so that the main heating section 31 can be heated by electricity within the cavity formed by the fixed seat 50 and the bottom wall 41 of the cover.

[0046] Combined Figure 6 As shown in the illustrated embodiment, the outer diameter of the heated main body segment 31, that is, the diameter of the outer contour line 33 on which the projection of the outer contour of the heated main body segment 31 lies, is smaller than the outer diameter of the bottom wall 41 of the cover, thereby allowing the heated main body segment 31 to be completely pressed against the bottom wall 41 of the housing cover 40. Similarly, the outer diameter of the heated main body segment 31 is smaller than the outer diameter of the fixing seat 50, so that the heated main body segment 31 is completely pressed against the bottom wall 41 of the cover and the bottom wall 52 of the seat, improving the fit between the heated main body segment 31 and the bottom wall 41 of the cover, and ensuring the heat transfer effect of the heating element 30.

[0047] In addition, the diameter of the hot body section 31 is smaller than the axial dimension D of the side wall 42 of the fixed seat 50, so that the hot body section 31 can be completely surrounded and covered by the fixed seat 50, reducing heat loss and improving the heating efficiency of the steam generator 20.

[0048] Reference Figure 6 and Figure 7 The bottom wall 41 of the housing has a recessed portion 43 that extends from the inside of the housing towards the outside. The steam generating device 20 also includes a fastener 60. The bottom wall of the recessed portion 43 is connected to the bottom wall 52 of the mounting base 50 via the fastener 60. When the fastener 60 is tightened, there is a pre-tightening force between the mounting base 50 and the housing 40, which makes the fit between the heating element 30 and the bottom wall 41 of the housing 40 tighter and the heat transfer efficiency higher. In addition, the connection structure between the mounting base 50 and the housing 40 is reasonably laid out, simple in structure, and easy to disassemble and assemble, reducing the maintenance cost of replacing the heating element 30.

[0049] The recess 43 has an internal structure with a cavity and an opening communicating with the top surface of the bottom wall 41 of the housing, facilitating the installation of the fastener 60 into the recess 43 from inside the housing 40. In particular, when the fastener 60 is installed into the recess 43 and the bottom wall 52, the head of the fastener 60 is submerged in the recess 43, preventing the fastener 60 from protruding from the top surface of the bottom wall 41 of the housing, thereby preventing the fastener 60 from protruding from the top surface of the bottom wall 41 of the housing and affecting the placement of the water container 21 inside the housing 40.

[0050] Reference Figure 6 and Figure 7 The steam generator 20 also includes a sealing ring 62. The bottom wall of the recess 43 is provided with a mounting hole 44 for the fastener 60 to pass through. The sealing ring 62 is fitted onto the edge of the mounting hole 44, so that the fastener 60 is sealed with the bottom wall of the recess 43 through the gasket 61. This helps to prevent moisture from falling into the housing 40 during the use of the steam generator 20 from seeping into the space where the heating element 30 is located, thereby preventing the heating element 30 from short-circuiting and being damaged, and avoiding malfunction of the steam generator 20.

[0051] Reference Figure 6 and Figure 7 The mounting base 50 has a flanged hole 54 protruding outwards, and the inner wall of the flanged hole 54 is threaded. The fastener 60 is a threaded connector. The threaded connector engages with the threaded part. When installing the mounting base 50 and the housing cover 40, the fastener 60 (i.e., the threaded connector) is passed through the mounting hole 44 and the flanged hole 54 in sequence and tightened, so that the end of the fastener 60 is screwed into the flanged hole 54, thereby connecting the mounting base 50 and the housing cover 40 together. The flanged hole 54 extends the connection length of the fastener 60 and the mounting base 50 in the axial direction D, making the connection between the fastener 60 and the mounting base 50 more stable.

[0052] This utility model also provides a cooking appliance, including a pot body 10, a lid and a steam generating device 20 as described above. The lid is detachably disposed on the pot body 10 and a cooking cavity 13 is formed between the two. The lid is provided with a steam conveying channel. The steam generating device 20 is disposed on the pot body 10 and communicates with the cooking cavity 13 through the steam conveying channel.

[0053] According to the cooking appliance of this utility model, the steam generated by the steam generator 20 enters the cooking chamber 13 through the steam delivery channel, thereby keeping the food in the cooking chamber 13 moist and improving the taste of the food.
