Description

Technical Field

[0001] This utility model relates to a cooking device. Background Technology

[0002] As modern families increasingly demand higher performance from kitchen appliances, cooking equipment, particularly steam ovens, has become a key focus for users, with heating efficiency and uniformity being crucial aspects of their functionality. Traditional cooking equipment typically uses a single magnetron, guiding microwaves into the oven cavity via a single waveguide to heat food. However, due to the limited power and microwave radiation range of a single magnetron, uneven microwave distribution within the oven cavity is common, especially when heating larger or irregularly shaped foods, resulting in significant differences in heating across different parts and affecting the overall heating effect. Therefore, dual-magnetron cooking equipment has emerged and is gradually becoming a representative of high-end cooking equipment.

[0003] However, the oven walls of existing cooking equipment have a certain degree of thermal conductivity, causing some heat inside the oven cavity to be conducted to the outside. This situation presents the following problems:

[0004] 1. For cooking appliances with dual magnetrons, the dual magnetrons located in the electrical cavity tend to generate more heat, leading to increased heat dissipation requirements for the electrical cavity. If the traditional oven cavity structure is still used, the heat transfer from the oven cavity to the electrical cavity will undoubtedly further increase the heat dissipation load on the electrical cavity, which may also lead to excessively high temperatures inside the electrical cavity and even cause high-temperature damage to electrical components.

[0005] 2. In low-voltage environments (such as Japan, which often uses 110V electricity), or when facing extremely high-temperature cooking needs (such as grilling functions), as some of the heat inside the oven cavity is conducted to the outside of the oven cavity, the heating rate inside the oven cavity will slow down, making it difficult for existing cooking equipment to provide extremely high-temperature cooking functions, or even to reach the required cooking temperature, resulting in poor cooking results.

[0006] At the same time, the extremely high temperature cooking mode of conventional cooking equipment often makes it difficult to ensure the uniformity of temperature distribution inside the oven cavity, which can easily lead to local overheating and cause food to burn in certain areas.

[0007] Therefore, this application is hereby submitted. Utility Model Content

[0008] In view of this, the present invention aims to propose a cooking device to solve the problems of conventional cooking devices in the prior art that are unable to provide extremely high temperature cooking functions (such as grilling functions) or have poor extremely high temperature cooking effects, as well as the poor uniformity of temperature distribution in the oven cavity causing localized burning of food under extremely high temperature cooking requirements.

[0009] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0010] A cooking device includes a heat-insulating cavity assembly and a heating assembly. The heat-insulating cavity assembly includes an inner cavity assembly and a heat-insulating frame assembly arranged sequentially from the inside to the outside. A heat-insulating element is disposed between the inner cavity assembly and the heat-insulating frame assembly. The heating assembly is disposed between the inner cavity assembly and the heat-insulating element. A heat-insulating structure is disposed on the outer side of the heat-insulating frame assembly.

[0011] Furthermore, the heat insulation component between the top plate of the inner cavity assembly and the top frame of the heat insulation frame assembly is referred to as the top heat insulation component; the heating assembly is disposed between the top plate and the top heat insulation component, and an upper heat insulation layer is disposed on the side of the top frame away from the top heat insulation component.

[0012] Furthermore, the top insulation component and the upper insulation layer are respectively snapped onto the top frame.

[0013] Furthermore, the heating assembly includes, from top to bottom, a wiring terminal, a first insulating sheet, a heating element, and a second insulating sheet, with the wiring terminal connected to the heating element.

[0014] Furthermore, the first insulating sheet is provided with wiring holes, and the wiring terminal is connected to the heating element through the wiring holes.

[0015] Furthermore, the top frame is provided with an inspection port, and the top heat insulation component is provided with a clearance opening. The inspection port and the clearance opening face each other and are both located above the wiring terminals.

[0016] Furthermore, a third insulating sheet is provided above the inspection port on the top frame, and a limiting claw is provided on the upper surface of the top frame, and the third insulating sheet can be engaged with the limiting claw.

[0017] Furthermore, the cooking device includes a fixing member disposed between the top frame and the top plate of the inner cavity assembly, and connected to the top frame and the top plate.

[0018] Furthermore, the top insulation component is provided with a first limiting opening, the first insulating sheet is provided with a second limiting opening, and the second insulating sheet is provided with a third limiting opening. One side of the fixing component is connected to the top plate, and the other side extends upward and passes through the third limiting opening, the second limiting opening, and the first limiting opening in sequence, and is connected to the top frame.

[0019] Furthermore, the first insulating sheet, the second insulating sheet, and the third insulating sheet are all mica sheets.

[0020] Compared with the prior art, the cooking device of this utility model has the following advantages:

[0021] The cooking device described in this utility model has an additional heating component installed between the inner cavity component and the heat insulation component to directly heat the plate structure of the inner cavity component. On the one hand, this can provide more heat to the oven cavity, enabling the cooking device to provide higher cooking temperatures and achieve ultra-high temperature cooking. On the other hand, by heating the inner cavity component, the heat is then conducted from the entire plate structure of the inner cavity component to the oven cavity, which can improve the uniformity of temperature distribution in the oven cavity, ensure the ultra-high temperature cooking effect on food, and avoid the occurrence of local burning of food.

[0022] Meanwhile, this embodiment further incorporates a heat insulation structure on the outer side of the heat insulation frame assembly, forming a double-layer heat insulation structure. Compared with the oven cavity of conventional cooking equipment, this effectively prevents heat transfer from the oven cavity to the outside. On the one hand, it provides heat insulation and prevents heat transfer from the oven cavity to the electrical cavity, thus avoiding excessive heat load in the electrical cavity due to heat transfer, and even preventing excessive temperature in the electrical cavity and high-temperature damage to electrical components. On the other hand, it effectively concentrates heat in the oven cavity, ensuring a good heating rate and quickly reaching the required cooking temperature (such as the extremely high temperature cooking requirements under the grilling function), which helps improve cooking efficiency and ensures cooking results. Correspondingly, this application also reduces energy loss and waste caused by heat transfer from the oven cavity to the outside, and can effectively reduce power consumption under the same cooking conditions.

[0041] The inventive concepts of this disclosure will be described below using terminology commonly used by those skilled in the art to convey the essence of their work to others skilled in the art. However, these inventive concepts may be embodied in many different forms and should not be construed as limited to the embodiments described herein.

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other. Directional terms used in this application refer to the orientation of the cooking equipment in its conventional assembly and placement state. (Refer to the attached document.) Figure 1 The coordinates in the diagram.

[0043] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] Example 1

[0045] To address the problems in existing technologies where heat easily escapes from the oven cavity, leading to increased heat dissipation load on the electrical cavity or slower heating rate within the oven cavity, this embodiment proposes a cooking device, as shown in the attached diagram. Figure 1-15As shown, the cooking device includes a heat-insulating cavity assembly 1. The heat-insulating cavity assembly 1 includes an inner cavity assembly 11 and a heat-insulating frame assembly 2 arranged sequentially from the inside to the outside. A heat-insulating element 20 is provided between the inner cavity assembly 11 and the heat-insulating frame assembly 2. The heat-insulating element 20 is snapped into the heat-insulating frame assembly 2. The heat-insulating frame assembly 2 is connected to the inner cavity assembly 11.

[0046] The inner cavity assembly 11 has the same structure as the inner cavity of a conventional cooking device, including a top plate 111, a left side plate 112, a bottom plate 113, a right side plate 114, and a rear plate 115. The connection between these plates, and whether they are integrated or separate, can be found in existing technology and will not be elaborated upon. The material of the heat insulation component 20 can be conventional heat insulation cotton or other conventional heat insulation materials; this application does not impose specific limitations on it. In this application, heat insulation components 20 are provided on the outer walls of the top plate 111, the left side plate 112, the bottom plate 113, the right side plate 114, and the rear plate 115, and are assembled and fixed by the heat insulation frame assembly 2.

[0047] Therefore, this application provides a heat insulation element 20 surrounding the outer wall of the entire inner cavity assembly 11, and assembles and fixes it through the heat insulation frame assembly 2 to form a heat insulation cavity assembly 1. Compared with the oven cavity of conventional cooking equipment, this can effectively prevent heat from the oven cavity from being transferred to the outside. On the one hand, it provides heat insulation and heat resistance, preventing heat from the oven cavity from being transferred to the electrical cavity 105 (attached). Figure 1 The invention eliminates electrical components such as magnetrons in the electrical cavity 105, avoiding excessive heat transfer load within the electrical cavity 105 and preventing overheating and damage to electrical components. On the other hand, it effectively concentrates heat in the oven cavity, ensuring a good heating rate and quickly reaching the required cooking temperature (such as the extremely high temperature cooking requirements under grilling function), thus improving cooking efficiency and ensuring cooking results. Correspondingly, this application also reduces energy loss and waste caused by heat transfer from the oven cavity to the outside, effectively reducing electrical energy consumption under the same cooking conditions.

[0048] At least a portion of the structure of the heat insulation frame assembly 2 is connected to the inner cavity assembly 11 by fasteners. An assembly space 28 is formed between the side of the heat insulation frame assembly 2 facing the inner cavity assembly 11 and the outer wall of the inner cavity assembly 11. The heat insulation element 20 is disposed within the assembly space 28, thereby enabling a relatively secure assembly between the heat insulation frame assembly 2 and the inner cavity assembly 11, and also ensuring a relatively secure placement of the heat insulation element 20 between them. Since the heat insulation element 20 often possesses a certain degree of deformation capability, it is interference-fitted within the assembly space 28 to further guarantee its stable placement.

[0049] For the assembly of the heat insulation component 20, the heat insulation frame assembly 2 is provided with a plurality of limiting pieces 27 on the side facing the inner cavity assembly 11. The limiting pieces 27 abut against the outer edge of the heat insulation component 20, and / or the heat insulation component 20 is provided with an insertion interface, and the limiting pieces 27 can pass through the insertion interface, thereby realizing the snap-fit ​​between the heat insulation component 20 and the heat insulation frame assembly 2.

[0050] The entire heat insulation rack assembly 2 includes a top frame 21, a left side frame 22, a bottom frame 23, a right side frame 24, and a rear frame 25. The top frame 21, left side frame 22, bottom frame 23, and right side frame 24 are connected end-to-end, enclosing an accommodating space. The inner cavity assembly 11 is disposed within this accommodating space. The rear frame 25 is connected to the inner cavity assembly 11, and / or the rear frame 25 is connected to at least one of the top frame 21, left side frame 22, bottom frame 23, and right side frame 24. That is, the heat insulation rack assembly 2 of this application has a similar structural configuration to the inner cavity assembly 11, both having five parts: top, left, bottom, right, and rear. This allows the cooking equipment, except for the front side, to have heat insulation components 20 on all five other sides to improve heat insulation, heat resistance, and heat retention effects.

[0051] Correspondingly, the top frame 21 corresponds to the top plate 111 of the inner cavity assembly 11, forming an assembly space 28 between them, and a heat insulation component 20 is provided. At the same time, the top frame 21 is provided with a limiting piece 27 extending toward the top plate 111 to limit the heat insulation component 20. The left side frame 22, bottom frame 23, right side frame 24, and rear frame 25 also correspond one-to-one with the left side plate 112, bottom plate 113, right side plate 114, and rear plate 115 of the inner cavity assembly 11, respectively, forming an assembly space 28 and providing corresponding heat insulation components 20. They are also provided with corresponding limiting pieces 27 to limit the corresponding heat insulation components 20. These will not be described in detail.

[0052] Regarding the connection of the rear frame 25, this application preferably specifies that the rear frame 25 is connected to at least the rear plate 115 of the inner cavity assembly 11, for example, through fasteners. Accordingly, the rear frame 25 is provided with corresponding mounting holes 251. Of course, if other plate structures of the inner cavity assembly 11 are connected to the rear plate 115 through bending and flanging, then the rear frame 25 can also be connected together with the rear plate 115 and the other plate structures of the inner cavity assembly 11.

[0053] Based on this, considering the reliable assembly between the heat insulation frame assembly 2 and the inner cavity assembly 11, in this application, in addition to the connection between the rear frame 25 and the rear plate 115, the rear frame 25 can also be connected to at least one of the top frame 21, the left side frame 22, the bottom frame 23, and the right side frame 24. This can be used as a first embodiment to achieve a reliable assembly between the heat insulation frame assembly 2 and the inner cavity assembly 11.

[0054] This embodiment also proposes a second implementation method, see attached document. Figure 1 , 12 The cooking device includes a front panel 106, which is connected to the inner cavity assembly 11, the same as in the prior art, and will not be described in detail. In addition, the cooking device includes a connector 107, at least one of the top frame 21, left side frame 22, bottom frame 23, and right side frame 24 can be connected to the front panel 106 through the connector 107. Thus, while the rear frame 25 is connected to the rear panel 115, the frame formed by the top frame 21, left side frame 22, bottom frame 23, and right side frame 24 can also be connected to the inner cavity assembly 11 through the connection relationship between the connector 107 and the front panel 106, which can also achieve a reliable assembly between the heat insulation rack assembly 2 and the inner cavity assembly 11.

[0055] Furthermore, this embodiment also proposes a third implementation method, as detailed in the appendix. Figure 13 The cooking device includes a fixing member 12, which is disposed between the top frame 21 and the top plate 111 of the inner cavity assembly 11, and is connected to the top frame 21 and the top plate 111 respectively, thereby enabling a secure assembly between the heat insulation rack assembly 2 and the inner cavity assembly 11.

[0056] Specifically, the top frame 21 is provided with a fixing area 213, the top plate 111 is provided with an assembly groove 1111, the lower end of the fixing member 12 is disposed in and connected to the assembly groove 1111, and the upper end of the fixing member 12 is connected to the fixing area 213. For example, the fixing member 12 includes a mounting base plate 121, the mounting base plate 121 is provided with a protrusion 123, the protrusion 123 extends upward, the protrusion 123 is connected to the fixing area 213 by fasteners, and correspondingly, the fixing area 213 is provided with a first fixing hole 215; the mounting base plate 121 is connected to the assembly groove 1111 by fasteners.

[0057] To improve assembly convenience, the fastener 12 is provided with upwardly extending insert plates 122 on both sides, and the fixing area 213 is provided with a socket 214. The insert plates 122 can be inserted into the socket 214, so that during assembly, the insert plates 122 and the socket 214 can form a positioning pre-assembly, which helps to improve the assembly convenience of the top frame 21 and the fastener 12.

[0058] Of course, this application is not limited to these three implementation methods, and these three implementation methods can be combined in any way.

[0059] Reference Appendix Figure 6-11 This application describes the various components in the heat insulation frame assembly 2.

[0060] The top frame 21 has a left flange 211 on its left side and a right flange 212 on its right side. The left flange 211 has a first groove 2111, and the right flange 212 has a second groove 2121. The left side frame 22 has an upper flange 221 on its upper side, which connects to the first groove 2111. The right side frame 24 has an upper flap 241 on its upper side, which connects to the second groove 2121. This achieves the connection between the top frame 21, the left side frame 22, and the right side frame 24. Preferably, the top frame 21, the left side frame 22, and the right side frame 24 are connected by fasteners.

[0061] A left flap 231 is provided on the left side of the base frame 23, and a right flap 232 is provided on the right side of the base frame 23. The left flap 231 has a third groove 2311, and the right flap 232 has a fourth groove 2321. A lower flange 222 is provided on the lower side of the left side frame 22, and the lower flange 222 is connected to the third groove 2311. A lower flap 242 is provided on the lower side of the right side frame 24, and the lower flap 242 is connected to the fourth groove 2321. This achieves the connection between the base frame 23, the left side frame 22, and the right side frame 24. Preferably, the base frame 23, the left side frame 22, and the right side frame 24 are connected by fasteners.

[0062] Example 2

[0063] This embodiment is a further introduction based on Embodiment 1, specifically addressing the problem that conventional cooking equipment has difficulty providing extremely high temperature cooking functions (such as grilling functions) or has poor extremely high temperature cooking effects.

[0064] It should be noted that the cooking device in this embodiment also has a bottom heater (not shown), which is disposed inside the inner cavity assembly 11 and located on the bottom plate 113 of the inner cavity assembly 11. This is the same as the prior art and will not be described in detail.

[0065] In addition, the cooking device includes a heating component 3, which is disposed between the inner cavity component 11 and the heat insulation component 20, and a heat insulation structure is provided on the outer side of the heat insulation frame component 2.

[0066] Therefore, in addition to the conventional bottom heater, this embodiment additionally provides a heating component 3 between the inner cavity component 11 and the heat insulation component 20 to directly heat the plate structure of the inner cavity component 11. On the one hand, this can provide more heat to the oven cavity, enabling the cooking equipment to provide higher cooking temperatures and achieve ultra-high temperature cooking function. On the other hand, by heating the inner cavity component 11, the heat is conducted from the entire plate structure of the inner cavity component 11 to the oven cavity, which can improve the uniformity of temperature distribution in the oven cavity, ensure the ultra-high temperature cooking effect on food, and avoid the occurrence of local burning of food.

[0067] Meanwhile, based on the beneficial effects of heat insulation, heat blocking, and heat concentration in Embodiment 1, this embodiment further sets up a heat insulation structure on the outside of the heat insulation frame assembly 2 to form a double-layer heat insulation structure, which reduces heat conduction to the outside, helps to further improve cooking efficiency and ensure cooking results.

[0068] The heating component 3 can be installed at any position between the inner cavity component 11 and the heat insulation component 20. Of course, the outer side wall of the heat insulation frame component 2 can be provided with heat insulation structure, or heat insulation structure can be provided on one or several side walls.

[0069] However, considering factors such as the overall volume of the heat insulation cavity assembly 1, the heat superposition between the heating assembly 3 and the bottom heater, and the degree of high-temperature impact on the electrical cavity 105, this application proposes a preferred solution, specifically:

[0070] For ease of description, the heat insulation component 20 between the top plate 111 of the inner cavity assembly 11 and the top frame 21 of the heat insulation frame assembly 2 is referred to as the top heat insulation component 201; the heating component 3 is disposed between the top plate 111 and the top heat insulation component 201, and an upper heat insulation layer 26 is disposed on the side of the top frame 21 away from the top heat insulation component 201, and the upper heat insulation layer 26 is snapped into the top frame 21.

[0071] Therefore, in this embodiment, the heating component 3 is preferably provided in the top structure of the heat insulation cavity component 1, and an additional upper heat insulation layer 26 is provided. On the one hand, it can be set opposite to the conventional bottom heater, so that the heat can be evenly distributed throughout the entire oven cavity from top to bottom and from bottom to top, and no local overheating will occur. On the other hand, since in conventional cooking equipment, the electrical cavity is often a certain distance away from the top of the cooking equipment (for example, the electrical cavity 105 of this application is set on the base 104 of the cooking equipment), combined with the double-layer heat insulation structure, the heat provided by the heating component 3 will not affect the heat dissipation load of the electrical cavity 105.

[0072] Furthermore, in this embodiment, the upper heat insulation layer 26 is preferably provided only on the top frame 21. This ensures that the heat insulation cavity assembly 1 has a good heat insulation effect while minimizing the overall volume of the heat insulation cavity assembly 1. Regarding the connection between the top frame 21 and the upper heat insulation layer 26, the top wall of the top frame 21 is provided with an upwardly extending limiting piece 27, which abuts against the outer edge of the upper heat insulation layer 26. Alternatively, the upper heat insulation layer 26 is provided with an insertion interface, through which the limiting piece 27 can pass.

[0073] The heating assembly 3 includes, from top to bottom, a terminal block 31, a first insulating sheet 32, a heating element 33, and a second insulating sheet 34. The terminal block 31 is connected to the heating element 33, which can be a conventional heating wire, heating plate, etc. Thus, while ensuring heating functionality, the first insulating sheet 32 ​​is placed between the top insulation component 201 and the heating element 33, and the second insulating sheet 34 is placed between the top plate 111 and the heating element 33, preventing the insulation cavity assembly 1 from becoming electrified and causing electric shock to the user. The first insulating sheet 32 ​​has a wiring hole 321, through which the terminal block 31 can be electrically connected to the heating element 33.

[0074] Since the heating component 3 is located in the sandwich structure of the heat insulation cavity component 1, in order to facilitate the wiring and maintenance of the heating component 3, the top frame 21 is provided with an inspection port 216, and the top heat insulation component 201 is provided with a clearance port 2011. The inspection port 216 and the clearance port 2011 are directly opposite each other and are both located above the wiring terminal 31. Thus, the upper heat insulation layer 26 can be removed, and the heating component 3 can be wired, routed, and maintained through the inspection port 216 and the clearance port 2011.

[0075] To avoid unnecessary electric shock risks, the top frame 21 is provided with a detachable third insulating sheet 218 above the inspection port 216. The upper surface of the top frame 21 is provided with a limiting claw 217. The third insulating sheet 218 can be engaged with the limiting claw 217. This can avoid safety risks to the heating component 3 at the inspection port 216. On the other hand, the detachable design of the third insulating sheet 218 facilitates maintenance operations and prevents foreign objects from entering through the inspection port 216.

[0076] The first insulating sheet 32, the second insulating sheet 34, and the third insulating sheet 218 are all preferably mica sheets, which have good insulation properties.

[0077] In Embodiment 1, the top frame 21 and top plate 111 are connected by a fastener 12, and this embodiment retains this implementation method. However, it should be noted that the top insulation component 201 is provided with a first limiting port 2012, the first insulating sheet 32 ​​is provided with a second limiting port 322, and the second insulating sheet 34 is provided with a third limiting port 341. This allows one side of the fastener 12 to connect to the top plate 111, and the other side to extend upwards, sequentially passing through the third limiting port 341, the second limiting port 322, and the first limiting port 2012, and connecting to the top frame 21. This avoids unnecessary spatial interference caused by the placement of the heating component 3, and the multiple limiting ports limit the movement between the top insulation component 201, the heating component 3, and the fastener 12, which to some extent improves the reliability of the connection between the top frame 21, the heating component 3, and the top plate 111. The heating component 33 only needs to be arranged to simply bypass the corresponding limiting port, and there will be no spatial interference between the heating component 33 and the fastener 12.

[0078] In this utility model, the technical content described in this embodiment can be adopted for any cooking device, such as a microwave oven or a steam oven. Based on the relevant structure and assembly relationship provided in this application, the cooking device also includes conventional components such as a door 101, a main shell 102, a rear shell 103, and electrical control components. Since these conventional components can all adopt existing technology, they will not be described in detail here.

[0079] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
