Description

•200940203 九、發明說明 相關申請案交互參考 本申請案請求2007年12月21日申請之美國第 61/016434號暫時專利申請案（發明名稱爲：高強度三維 ： 構造和製造方法）的優先權。該暫時申請案的全部內容倂 费 入本案’做各種目的之參考。 本申請案請求2008年10月02日申請之美國第 φ 61/1 02346號暫時專利申請案（發明名稱爲：彎折的三維 構造）的優先權。該暫時申請案的全部內容倂入本案，做 各種目的之參考。 【發明所屬之技術領域】 本發明大致關於可變通（彈性：flexible )的製造製 程，例如使用衝孔（punching)、沖壓（stamping)、輥 壓成形、和類似的製程準備片體材料供彎曲，然後將該等 〇 片體彎曲成剛性的三維構造。本發明的各種態樣是關於以 可調整的結構形成烹飪器具（appliance)。 【先前技術】 大量生產三維構造的習且知技術，要求複雜且勞力密 集的組合製程。一般而言，將分離的片體材料和固體元件 固定在一起，以形成該構造。當最終產品增加複雜度，則 組合製程變得急劇地增加複雜性和成本。此習知技術遭受 缺乏可變通性和成本壓力之苦。 -5- 200940203 藉由例子的方式，習知器具（例如烹飪灶）要求組合 生產線和製造系統的設計及工程像一些已生產之產品~樣 地複雜。因此，組合生產線和生產設施難以修改。同樣地 ，因爲要增加規模的效率及使單位成本最小化，所以器具 的配置和結構受到限制。 習知的烹飪灶和爐包括骨架式的框架和殼體，以支撐 一或更多烹飪隔室。每一隔室包括頂部、本體、和底部構 件，其是由多個片體材料和其他組件固定再一起成爲三維 構造而形成。灶或器具進一步要求複雜的構造（例如前和 後框架構造），以增加產品的剛性。每一類型的灶也要求 獨特的組合製程。例如具有保溫抽屜（warming drawer ) 的烹飪灶相較於包括二烹飪隔室的烹飪灶，要求不同的隔 室和不同的骨架構造。 爲了利用規模效率，就每一獨特的烹飪灶結構設立組 合生產線和製程。製造者通常設計「灶生產線」以適合各 種尺寸和結構。製造者針對每一灶生產線準備特定的工具 。當大幅地改變工程設計時，必須隨著修改製造生產線。 同樣地，當（例如）在多個爐設計和單一爐設計之間變化 時，灶生產線難以輕易地改變或有效率地節省成本。 再者，當訂購零件時，製造者必須估計每一灶生產線 將製造的產品總數。必須提供大數目的特定零件，每一零 件對特定的灶生產線都是關鍵。當增加或減少生產時，材 料的成本和浪費也增加。因爲這些和其他理由，就器具的 典型生產線而言，安裝工具裝備的投資會達數百萬元；而 -6 - •200940203 對高容量的器具生產線而言，安裝工具裝備的投資會達數 千萬元。 近年來，已發展出由二爲片體材料形成三維產品（例 如烹飪器具）的方法。此方法大致降低工具準備和生產成 本，且增加製造可變通性。爲了此目的，已發展出製備片 體材料供沿著所欲的彎曲生產線精密彎折的各種方法。例 如美國第 US 6877349、 6877349、 7032426、 7152449、 ❹ 71 52450號專利案描述製備和彎折片.體材料的各種方法， 該等方法用於從實質平坦的二維片體形成具有相對高公差 的三維物體。上述專利案中所顯示和描述的彎折構造促進 所謂「邊對面」的嚙合，和有利於沿著所欲彎曲線彎折的 現象。 上述專利案中所描述的方法和構造，可用於在各種應 用中形成三維構造。由於認知到此等方法的優點，所有有 需要擴展此等方法的有益應用。 © 相較於熔接構造，上述方法提供具有強度和剛性的三 維構造，但是在許多例子中，希望提供能承受增加荷重的 三維構造。例如可希望形成大的複雜構造，其具有滿足設 計要求的充分強度，而不必使用（或至少減少需求）額外 的修飾來增加強度。此等額外修飾可包括熔接或附接強化 構件（例如板、角板、或其他補強構件）在接合處、增加 材料的厚度、或使用支撐構造。在一些情況中’即使使用 支撐構造，也無法將構造強度增加至充分的程度。在其他 情況中，在成本考量上，禁止使用增加材料帳單的此等附 200940203 加構造。 在烹飪器具的內容中，有例如累積油脂、食物、和其 他材料在烹飪表面的額外問題。此油脂和碎屑是混亂的、 步雅觀的、且有味道。在高的操作溫度，油脂會造成火災 。油脂和其他東西的累積會減少內部表面的熱反射性，所 以也會降低器具的效能。使用上述的彎折技術有該等缺點 ，因爲縫隙、槽、和類似者爲油脂的累積和聚集特別提供 麻煩的來源（在縫隙內和沿著彎曲部的鉤）。 習知器具已使用拋棄式內襯和自我清潔式循環，以減 少或消除堆積的油脂。烹飪用具（例如鍋子和平底鍋）通 常使用不沾黏的塗層，但是目前此塗層應用於爐隔室已不 經濟。施加塗層至習知爐導致高成本的其中一個因素是： 需覆蓋大表面積。因爲習知爐是由大量的零件組合而成。 而在處理時，每一零件都需完全覆蓋，所以需要覆蓋的總 表面積非常地大。此外，在組合期間，當受到習知製程所 涉及的彎曲、扭曲、和被各種運動零件撞到時，例如聚合 體（譬如鐵弗龍或聚四氟乙烯（PTFE ))和玻化釉容易變 成碎片或從表面剝離。因此，如果要使用塗層的話’是在 組合後才施加塗層。 當塗層使用在供彎折之片體材料時，塗層的剝離特別 地麻煩。在彎折期間，沿著彎曲線的片體材料遭受彎曲、 扭曲、和伸展。非彈性且剛性的塗層易於沿著彎曲線從片 體剝離。由於片體和其所黏著的片體表面之間不同的伸展 率，所以即使較可撓的塗層也有分離的傾向。 -8- *200940203 器具製造者關心的另一問題是：使烹飪空間最大化， 但不會增加器具整體的尺寸或犧牲構造的整合性。使用附 加的支撐構造和類似者至已彎曲片體或已組合框架，會減 少可用於烹飪的空間量。 所需要的是克服上述及其他缺點的三維構造和製造方 法。所需要的是能以可變通且節省成本之製造技術生產的 構造。所需要的是降低相關成本的剛性構造。所需要的是 φ 可調整的構造性結構和設計。 所需要的是由彎折片體材料所形成的三維構造，其能 使上述彎曲線問題最小化。 【發明內容】 本發明的各種態樣導向一種三維構造，包含：殼體， 由包括有複數彎曲線的至少一個二維片體材料所形成，其 界定該殼體的外部側面，該等彎曲線中至少二者包括沿著 Ο 該等彎曲線的定位構造；和在殼體內的內部構造，該內部 構造具有周圍和複數支撐凸緣，該複數凸緣從該周圍向外 延伸，每一支撐凸緣朝向該殻體的個別彎曲線延伸，且每 一支撐凸緣包括在其外部邊緣上的固定構造。建構每一內 部構造支撐凸緣的該固定構造，以配合該殻體的個別定位 構造，以將該內部構造支撐在該殼體內。 在各種實施例中，該定位構造是彎曲控制位移。每一 彎曲線可包括複數彎曲控制位移。 可建構至少一支撐凸緣被固定至殼體，且無須分離的 -9- 200940203 固定件。該複數支撐凸緣中至少二者可從該內部構造的相 反側面延伸。該內部構造可由至少一內部片體材料形成， 且該至少一內部片體包括內部彎曲線，且該內部構造之該 等支撐凸緣中至少一者可和該至少一內部片體整體形成， 且該內部彎曲線界定內部側面和該等支撐凸緣中至少一者 之間的邊界。該至少一支撐凸緣可實質地直的。該至少一 支撐凸緣可與該內部側面所界定之平面成實質地45度地 從該內部構造延伸至該殼體。 在各種實施例中，該內部構造由至少一片體材料形成 ，且該至少一片體包括複數內部彎曲線，且該內部構造之 至少二支撐凸緣和該至少一片體整體形成，且該等內部彎 曲線界定該內部側面和該至少二支撐凸緣之間的邊界。 至少一固定構造可包括垂片，且個別定位構造包括沿 著殻體之個別彎曲線的孔，且其中該垂片插入該孔內，藉 此將該內部構造的個別支撐凸緣固定至該殼體。該內部構 造可由至少二片體材料所形成，每一片體材料具有內部彎 曲線。該二片體之一和該內部構造之該等支撐凸緣之至少 其一可整體形成，且該二片體之一的該內部彎曲線界定該 內部側面和該等支撐凸緣之至少其一之間的邊界。該二片 體之另一者可包括唇部，其中該二片體之另一者的該內部 彎曲線界定另一內部側面和該唇部之間的邊界，且該唇部 向該內部構造延伸。該唇部可固定至該等支撐凸緣之該至 少一者。該唇部不需分離的固定器便可固定至該至少一凸 緣。 -10- '200940203 可建構該殼體供安裝模組控制面板至該殼體。該殼體 可包括至少一孔，該孔提供電線用的引導路徑。 在各種實施例中，該三維構造是器具。在各種實施例 中，該三維構造是爐。 本發明的各種態樣導向一種三維構造，包含：片體材 料，沿著複數彎曲線彎曲，該已彎曲的片體材料形成複數 壁，該複數壁界定內部容積且具有預定的橫剖面，至少一 ❹ 彎曲線在該等壁其中之一內界定向外彎折垂片部份。該垂 片具有和該預定橫剖面互補的周圍形狀。該已彎折之垂片 的至少一側面嚙合立即鄰接的對應壁，藉此界定該複數壁 的預定橫剖面。 在各種實施例中，該垂片部份嵌套在該內部容積內。 在各種實施例中，該垂片部份的該周圍緊接該各複數壁之 至少二對應壁。可建構該垂片部份以支撐該壁構造，且可 進一步建構該垂片部份當作用於該等壁的交叉支撐》 ❹ 複數彎曲促進構造可界定該複數彎曲線。該等彎曲促 進構造可爲位移。 在各種實施例中，該垂片部份固定至該複數壁中的任 意者。該垂片部份可不需固定件便可固定至該壁。該垂片 部份可扣合進入該內部容積。 在各種實施例中，該片體材料包括塗層。該三維構造 可爲爐殻體的一部份，且可以不沾黏塗層將該片體材料預 處理。該構造可爲一種器具。該器具可爲烹飪灶。< 本發明的各種態樣導向一種三維構造，包含：由片體 -11 -

The entire contents of this provisional application are included in the case's reference for various purposes. The present application claims priority to U.S. Patent Application Serial No. φ 61/1, 022, filed on Oct. 2, 2008, entitled. The entire contents of this provisional application are included in the case and are used for various purposes. TECHNICAL FIELD OF THE INVENTION The present invention generally relates to a flexible manufacturing process, for example, using punching, stamping, roll forming, and the like to prepare a sheet material for bending, The haptics are then bent into a rigid three-dimensional configuration. Various aspects of the invention are directed to forming an appliance in an adjustable configuration. [Prior Art] A well-known technique for mass-producing three-dimensional structures requires a complicated and labor-intensive combination process. In general, the separated sheet material and solid elements are secured together to form the construction. As the final product adds complexity, the combined process becomes dramatically increasing complexity and cost. This prior art suffers from a lack of flexibility and cost pressure. -5- 200940203 By way of example, conventional appliances (such as cooking stoves) require the design and engineering of combined production lines and manufacturing systems to be as complex as some of the products that have been produced. Therefore, combined production lines and production facilities are difficult to modify. Similarly, the configuration and structure of appliances are limited because of the increased efficiency of scale and the minimization of unit costs. Conventional cooking hobs and ovens include a skeletal frame and housing to support one or more cooking compartments. Each compartment includes a top portion, a body, and a bottom member that are formed by a plurality of sheet materials and other components fixed together to form a three-dimensional configuration. Stoves or appliances further require complex constructions (such as front and rear frame construction) to increase the rigidity of the product. Each type of stove also requires a unique combination process. For example, a cooking hob with a warming drawer requires different compartments and different skeletal configurations than cooking hobs that include two cooking compartments. In order to take advantage of scale efficiency, a combined production line and process is set up for each unique cooking hob structure. Manufacturers often design "stool production lines" to suit a variety of sizes and configurations. The manufacturer prepares specific tools for each cooking line. When the engineering design is drastically changed, the manufacturing line must be modified as it is modified. As such, it is difficult to easily change or efficiently save cost when changing, for example, between multiple furnace designs and a single furnace design. Furthermore, when ordering parts, the manufacturer must estimate the total number of products that will be manufactured for each cooking line. A large number of specific parts must be provided, each of which is critical to a particular cooking line. When increasing or decreasing production, the cost and waste of materials also increases. For these and other reasons, the investment in installation tooling will reach several million yuan for a typical production line of appliances; and -6 - •200940203 for high-capacity appliance production lines, the investment in installation tools and equipment will reach several thousand Ten thousand yuan. In recent years, a method of forming a three-dimensional product (e.g., a cooking utensil) from a sheet material has been developed. This approach substantially reduces tool preparation and production costs and increases manufacturing flexibility. For this purpose, various methods have been developed for preparing sheet materials for precise bending along a desired bending line. For example, U.S. Patent Nos. 6,877,349, 6,877,349, 7,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Three-dimensional object. The bent configuration shown and described in the above patents promotes so-called "edge-to-face" engagement and a phenomenon that facilitates bending along the desired bend line. The methods and constructions described in the above patents can be used to form three-dimensional configurations in a variety of applications. Because of the recognition of the advantages of these methods, there is a need for beneficial applications that extend these methods. © The above method provides a three-dimensional construction with strength and rigidity compared to a welded construction, but in many instances it is desirable to provide a three-dimensional construction that can withstand increased loads. For example, it may be desirable to form large, complex structures that have sufficient strength to meet design requirements without having to use (or at least reduce the need for) additional modifications to increase strength. Such additional modifications may include welding or attaching reinforcing members (e.g., plates, gussets, or other reinforcing members) at the joint, increasing the thickness of the material, or using a support configuration. In some cases, even if a support structure is used, the structural strength cannot be increased to a sufficient extent. In other cases, such additional 200940203 plus constructions for increased material bills are prohibited for cost considerations. Among the contents of the cooking appliance, there are additional problems such as accumulation of grease, food, and other materials on the cooking surface. This grease and crumbs are confusing, sleek and tasteful. At high operating temperatures, grease can cause a fire. The accumulation of grease and other things reduces the thermal reflectivity of the internal surface and therefore the performance of the appliance. The use of the above-described bending technique has these disadvantages because the slits, grooves, and the like provide a particularly troublesome source (hooks in the slits and along the bends) for the accumulation and accumulation of grease. Conventional appliances have used disposable liners and self-cleaning cycles to reduce or eliminate accumulated grease. Cooking utensils (such as pots and pans) typically use a non-stick coating, but it is currently uneconomical to apply this coating to the furnace compartment. One of the factors that contribute to the high cost of applying a coating to a conventional furnace is that it requires a large surface area to be covered. Because the conventional furnace is made up of a large number of parts. At the time of processing, each part needs to be completely covered, so the total surface area to be covered is very large. In addition, during the assembly, when subjected to bending, twisting, and being hit by various moving parts, such as a polymer (such as Teflon or Polytetrafluoroethylene (PTFE)) and a vitrified glaze, it becomes easy to become Debris or peel off from the surface. Therefore, if a coating is to be used, the coating is applied after the combination. Peeling of the coating is particularly troublesome when the coating is applied to a sheet material for bending. During bending, the sheet material along the bend line suffers from bending, twisting, and stretching. The inelastic and rigid coating tends to peel away from the sheet along the bend line. Due to the different elongation between the sheet and the surface of the sheet to which it is attached, even a more flexible coating has a tendency to separate. -8- *200940203 Another issue of concern to appliance manufacturers is to maximize cooking space without increasing the overall size of the appliance or sacrificing structural integrity. The use of additional support configurations and the like to the bent sheet or combined frame reduces the amount of space available for cooking. What is needed is a three dimensional construction and manufacturing method that overcomes the above and other disadvantages. What is needed is a construction that can be produced with flexible and cost effective manufacturing techniques. What is needed is a rigid construction that reduces the associated costs. What is needed is the φ adjustable structural structure and design. What is needed is a three-dimensional construction formed by bending the sheet material that minimizes the aforementioned bending line problems. SUMMARY OF THE INVENTION Various aspects of the present invention are directed to a three-dimensional construction comprising: a housing formed from at least one two-dimensional sheet material comprising a plurality of curved lines defining an outer side of the housing, the curved lines At least two of them include a positioning configuration along the curved line of the crucible; and an internal configuration within the housing having a perimeter and a plurality of support flanges extending outwardly from the periphery, each support projection The rim extends toward the individual bend lines of the housing, and each support flange includes a fixed configuration on its outer edge.

For the sake of convenience, various embodiments will be described herein with respect to an illustrative situation of a cooking hob. However, it will be appreciated by those skilled in the art that the invention described herein can be utilized in applications that require flexible and precise fabrication of three-dimensional construction. Therefore, the description of the appliance is merely illustrative. The technique of the present invention for precision bending can also be used to produce a number of seven-dimensional (3D) configurations including, but not limited to, electronic component backplanes, automotive components and backplanes, transport components and backplanes, building components and backplanes. , appliance parts and floors, truck components and floors, building and structural components, space components, commercial coolers, air conditioning (HVAC) systems, and more. The construction and method of the present invention can be used in a variety of applications, including residential, commercial, or industrial applications. That is, the technology of the present invention can be widely applied to various three-dimensional products and configurations' including products and structures which are bent from a two-dimensional sheet material. This three-dimensional construction is advantageous because the present invention also allows for a reduction in the height of the three-dimensional structure to facilitate repackaging and re-transport. These characteristics are suitable for the production of reusable shipping containers and the like. It will be appreciated by those skilled in the art that recent techniques for fabricating appliances and the like may involve the preparation of major components from one or more bent sheet materials. Using the -16- ‘200940203 bent sheet will reduce the tools, parts, time, and combination steps required to make the construction. These techniques utilize techniques for making sheet materials that are precisely bent along the desired bend line. For the purposes of various purposes, for example, U.S. Patent Nos. 6,481,259, 6,,,,,,,,,,,,,,,,,,,, These U.S. patents describe various methods of making and bending a sheet material from a substantially flat two-dimensional sheet to form a three-dimensional object having a relatively high tolerance. ❹ In many aspects, the sheet material of the present invention is similar to that disclosed in the following U.S. Patent Nos. 6,481,259, 6,877,349, 7,152,449, 7, 152, 245, U.S. Patent Application Serial No. 10/821,818, US Patent No. 703 2426, 7263 869, 72225 1 1 , US Patent Application No. 1 1/35 7934 (Announcement No. 2006/026 1 1 39), US Patent Application US No. 10/952357 (Announcement No. 2005/0064138), US Patent Application No. 11/384216 (Announcement No. 2006/0207212), US Patent Application US Ν〇·11/080288 (Announcement) US Patent No. 2005/0257589, U.S. Patent Application No. </RTI> </ RTI> </ RTI> </ RTI> <RTIgt; </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> US Patent Application No. 1 1 /1 803 98 (Announcement No. 200 6/0 021413), US Patent Application No. 11/290,968 (Announcement No. 2006/0075798), US Patent Application No. 11/411440 (Announcement No. 200 7/0113614), US Provisional Patent Application No. 60/ 665 5 77, US Patent Application No. 11/386463 (Announcement No. 2006/0277965), and the United States Time patent application US No. 60/854846. All of the above-mentioned patents and patent applications 200940203 are incorporated herein by reference for all purposes. Referring to Figure 1, cooking hob 230 includes a housing 232 and a plurality of cooktop assemblies generally designated 233. Some of the cooktop assemblies 2 3 3 may be pre-assembled components, and the remaining cooktop components may be combined on site. In some aspects, the cooking hob is similar to the conventional cooking hobs, such as those disclosed in U.S. Patent No. 2,423,863, issued toWal. The cooking hob may be provided with a cooking top or stove top, an oven 237, and a warming drawer 239, generally indicated at 235. As will be described below, the cooking range of the present invention allows the structure of the stove to be changed more easily. For example, the cooking hob can be provided with multiple ovens, microwave ovens, heated drawers, utility drawers, various cooked tops, and other components and consumer features. Materials suitable for use in cooking ranges and components include, but are not limited to, steel, stainless steel, aluminum, ceramics, porcelain, composites, and the like. It may be desirable to treat one or more stoves and components for aesthetic or functional purposes (e.g., to increase reflectivity or reduce accumulated grease). Such treatments may include additional coating materials such as lacquers, porcelain, enamel, polymers, and the like. Some or all of the cooking surface may be treated with a non-stick coating including, but not limited to, polytetrafluoroethylene, polytetrafluoroethene (PTEF), and vitreous. Laminates, chemical treatments, polishing, use of liners, and the like can also be utilized depending on the application. The material can be pretreated, i.e., processed prior to bending and/or combination. -18- 200940203 It is also possible to process materials after this process. The method of forming a structure of the present invention produces a number of advantages over conventional processing processes. In the case of applying a non-stick coating, applying and heating the ceramic material at the flat portion is faster and more uniform. Compared to the deformed and three-dimensional configuration, cleaning, polishing, and other processing, and final processing processes are easier to perform when processed in a flat sheet, and the cost can be reduced. Referring to Figures 2-6, the furnace 23 7 includes a bottom 249, and a furnace compartment 240 having a side wall 242, a Q top 244, and a back 246. Side wall 242, top 244, and back portion 24 6 together form body 247. Conventional furnace compartments are made by welding or joining together separate sheet materials to form wall sections. In various embodiments, the furnace compartment 240 can be formed by bending a sheet of material into a fixedly positioned furnace compartment. The sheet body can also be bent to form a body and a top cover that is fixed to the body to form a furnace compartment. The front side of the body may be covered by a conventional front frame member 251 or the front side may remain open. The front frame member increases the rigidity of the furnace compartment and is also used to secure the φ compartment within the housing 239. The furnace compartment includes a flange 253 that is secured to the front edge of the front frame member. The furnace compartment includes various other flanges and a fixed configuration for securing the barrier within the housing. Unlike conventional appliances, the construction of the present invention does not require complex front frame construction to provide rigidity to the overall construction and system. The aforementioned front frame member can be a thin sheet material. Although it can be constructed to constitute a rigid structural member, it is generally understood that the aforementioned compartment has improved its rigidity. Thus, the appliance and furnace compartment of the present invention reduces the billing and system complexity of the material while increasing flexibility, as compared to conventional appliances. -19- 200940203 Furnace body 247 may include features integrated into the construct to have a shelf, a rack, a sub-combination, a broiler, and the like. For example, the compartment includes a bracket 2 54, which engages a conventional shelf. The compartment may also include other features such as holes for venting air and convection fans. Compartment 240 includes a bottom 249 that can be attached to or detached from the compartment. The bottom portion can engage the grid body 24 or can support the body. In various embodiments, the bottom is disposed within the oven compartment and is removable. The position of the bottom in the compartment can be adjusted to modify the size and structure of the oven compartment without having to modify the entire furnace. With particular reference to Figures 9-12, the bottom 249 includes a heater element 256, an insulating layer 258, a top pan 260, and a bottom pan 261. An insulating layer is placed under the heater element and provides thermal insulation of the bottom pan. The top pan and bottom pan are covered with heater elements and insulation on at least two sides. The rear end of the bottom can remain open to help the heater element be inserted into the back side of the furnace. The front side of the bottom is shown closed by the top pan to protect the consumer from contact with the heater element and provides a pleasing aesthetic front side. The top pan 260 has a recessed top portion 263 having an outer lip 265. The outer lip helps keep food and grease on top of the bottom 249. In some cases, it may be desirable to provide a disposable or removable liner on top 2 63 to aid in the cleaning process. The top pan 260 includes an aperture 273 to allow combustion and/or convective heat to escape from the bottom 249, particularly the heater element 256. Fans and other components can be placed to allow gas to flow through the bottom. Although the bottom is described by the content of electric heating, it is generally understood that -20- •200940203 can modify the bottom depending on the application. The bottom and/or furnace may be constructed for gas, electrical, or other heating structures. For example, in the case of a convectionless electric furnace, the bottom can be sealed without holes. It is also possible to construct the bottom for radiation, infrared, microwave, or a combination of these (only a few). The structure of the heater element can also be modified depending on the desired performance parameters and other factors. Referring again to Figures 7-12, the furnace body 247 is constructed to receive the bottom 249. In various embodiments, the mount 267 is disposed on the side wall 242 and/or the back 246 φ to engage and secure the bottom within the furnace body. The mounting bracket shown in Figure 7-8 slidably engages the bottom. Specifically, the sides of the bottom include V-shaped grooves that are constructed to engage the rails to form the rails as mounting seats. The height of the bottom relative to the side wall can be adjusted by placing the bottom on a selected set of mounts. As will be appreciated by those skilled in the art, the bottom and furnace compartments can be modified from the foregoing description. For example, the bottom can be engaged with the furnace compartment by clips, hooks, tabs, and the like. Not all apps need to be removed or adjusted. ❹ In various embodiments, the bottom portion is permanently secured into a selected location within the furnace compartment during assembly. The means for securing the bottom to the oven compartment include, but are not limited to, rivets, twist-tabs, buttons, or more. As can be appreciated from the foregoing description, the furnace compartment can include any other structure that houses the bottom in various positions. The mount can be integrated with the side walls of the furnace compartment. The mount can include a linear profile and a slot profile to secure the bottom lock and/or positive haptic feedback during assembly. In various embodiments, grooves, slots, fasteners, and the like may be constructed on the back of the furnace body to engage the bottom 249. -21 - 200940203 The mount can also be used as a rack, whereby unused mounts can accommodate shelves and the like. During the assembly, a pair of complex mounts are selected depending on the structure of the furnace. The bottom is placed on the mount and is fixedly positioned. A connection joint 270 can be provided for each pair of mounts 267. Therefore, the bottom slides into position and engages the individual joints. The housing is then assembled around the furnace compartment. The bottom structure can also be connected to the furnace compartment by other configurations. For example, flexible wires can be used so that a single connector can be attached to various locations on the bottom.改变 The position of the bottom in the furnace can be changed depending on the application. For example, if it is desired that the position of the bottom be adjustable by the consumer, the oven may include a mount or other receiving member to adjustably receive and remove the bottom. In contrast, if it is desired to position the bottom by the manufacturer based on the type of product, the buildable bottom is permanently fixed in the furnace for positioning. Further, the appliance can be constructed similarly based on the intended use. For example, if the bottom can be adjusted by the user, the furnace can include a single gate that covers the entire furnace compartment; or if the bottom is permanently fixed by the manufacturer, the furnace can be fitted with multiple doors. Doors can also be constructed based on the application and appliance structure 0. For example, in contrast to the manner in which the doors are opened up and down, the door can be swung laterally. As will be appreciated by those of ordinary skill, the above-described construction provides more modularity relative to conventional constructions and appliances. As can be seen from the description herein, the construction and components can be modified to simply and precisely adjust the height, width, and other specifications. The position and orientation of the various combinations of the invention can be modified. The size and orientation can be modified, for example, by changing the shape of the sheet material and placing the bottom at the same position. -22- *200940203 As shown in Fig. 10, various structures can be obtained simply by adjusting the height and structure of the bottom portion 249 in the furnace compartment 240. Therefore, a single furnace compartment can accommodate a variety of furnace configurations. Furthermore, the structure can be adjusted simply by selecting the position at the bottom, without having to change the manufacturing setup, the assembly process, the ordering part program, and the like in a complicated manner. In various embodiments, the bottom portion 249 is disposed above the bottom surface of the furnace compartment side wall 242 and the second cooking or warming compartment is disposed below the bottom portion. The second cooking compartment may be heated by the bottom 249 or may be heated by an additional heating element, such as a heating element disposed within the floor of the stove. The bottom can also be constructed for erect orientation, thereby providing a side-by-side configuration. In various configurations, the appliance and furnace may also include more than one bottom.

在各種實施例中，爐本體247室由彎折單一片體材料 而形成。準備片體材料供在製造烹飪灶23 0的製程期間， 沿著彎曲線2 79彎曲和彎折。片體可爲單片的片體材料、 或數片片體接合在一起。在許多態樣中，本發明的片體材 Ο 料類似於下列專利案所揭露者：上述的‘259、‘349、‘426 、‘449、‘450號專利案、和第 US 10/821818 (公告第 2005/0005670

申請案、第US 11/411440 (公告第2007/0113614)號美國 專利申請案、第US 60/665577號美國暫時專利申請案、 第US 11/386463 (公告第2006/0 277965)號美國專利申請 案、和第US 60/854846號美國暫時專利申請案。該等專 利案和專利申請案的全部內容，都倂入本文做爲所有目的 的參考。 可想像到的其他有利彎曲的構造都在本發明的範圍內 。在彎曲期間，此等構造通常能夠找到位置且定位各別的 彎曲線。例如該等構造可用於決定片體材料中會發生彎曲 的位置，且也在彎曲期間可定位片體材料的各零件，括邊 緣、面、和類似者。可進一步將構造建構用於有利使用最 少的工具和力來彎曲材料片體。 一些應用可能要求具有增加反射率、減少累積油脂、 和其他特徵的表面。已經發現塗層和積層（laminates )可 提供改變形成爐隔室之材料特性的有效方法。但是當塗層 、積層、和類似者與使用上述技術製備的彎折片體一起使 時’會有變成碎片或剝落的傾向。片體材料遭受彎曲、扭 曲、伸展’該等步驟使得難以在彎曲線的區域內有效率地 塗覆。 特別參考圖7、13-14，片體材料272可包括改善使用 具有表面和材料準備之彎折技術的的構造。準備片體材料 -24- *200940203 具有複數有利彎曲的構造274’其界定彎曲線275。有利 彎曲的構造2 74可爲狹縫、槽、位移、洞、和類似者。 在各種實施例中，準備片體材料和彎曲線以形成重疊 構造2 77，其在離爐內部的遙遠位置密封彎曲線。彎曲線 將片體材料分割成第一部份279和第二部份281。第一部 份和第二部份的每一者包括預先形成的彎角凸緣282，其 界定預先形成的彎曲303’。角凸緣從相向於彎曲線的一端 〇 成一角度地延伸，使得在彎曲線每一側上的片體型成一角 度。在彎曲期間，第一部份和第二部份彼此接近，直到該 兩部份彼此緊靠。「緊靠（abut )」意指第一部份和第二 部份在一點對另一者施加接觸力。因此，第一部份重疊另 —者，藉此形成多個片體厚度的構架。本文所用之「重疊 構造」意指藉由彎折具有預形成角凸緣之材料片體，直到 第一部份和第二部份彼此鄰接爲止。 也可形成和彎曲片體，使得各個硬的預先形成的彎曲 G 303’彼此對其和相鄰。在各種實施例中，建構片體材料使 得片體的末端稍微彎曲通過一點，預先形成的彎曲在該點 接觸。在各實施例中，每一預先形成的彎曲略小於135度 。片體材料沿著彎曲線彎曲，直到各預先形成的彎曲相接 觸’其略大於90度。然後，再進一步彎曲片體，直到形 成90度的角隅，且以一壓力作用在各預形成彎曲的角之 間的接觸點，以使片體稍微預負載。以此方式，施加壓力 以增加片體重疊部份的密封。 雖然描述成「預形成」，但是一般人可瞭解，可在本 -25- 200940203 文之其他製程以前或以後形成角度。例如，可在沿著彎曲 線彎曲之前或之後，由質質平坦的片體形成凸緣。 如本文所述’ 「預形成的彎曲」意指剛性且固定的彎 曲。例如片體材料272類似沿著彎曲線結合的角托架。藉 由對材料加工或使用其他習知的技術以實行剛性彎曲角， 而形成每一預形成的角》對照上述的彎曲技術，加工材料 使材料受到永久的改變並保持其形狀。從另一觀點，預形 成的彎曲和彎曲線不同，因爲彎曲線的作用像鉸鏈，而預 形成的彎曲具有相對的剛性。實際上，加工材料以形成預 形成的彎曲，意欲改變片體的形狀並防止彈回。雖然上述 的彎曲技術促進彎曲，但是此等技術如果沒有額外的特徵 (例如扣合和角鎖固）則無法防止彈回其原始形狀。相較 之下，使用固定角度和形狀更像片體之原始形狀的習知技 術來形成預形成的彎曲。需要改變彎曲角度的能量類似於 彎曲片體任何其他部份所需的能量。 如圖13B-13C所示，前述的架構形成類似反斜角接合 。在已彎折位置中，第一部份和第二部份彼此實質平坦地 相底。預形成的彎曲角凸緣從第一和第二部份以預形成的 或預定的彎曲角延伸。預形成的彎曲角界定彎曲角凸緣的 基底，且每一部份的基底可彼此鄰接。彎曲線位在第一和 第二部份離預形成彎曲角的相反端。因此，彎曲線位在遠 離預形成彎曲角的嚙合區域。 雖然到現在爲止都將構造描述成片體彼此鄰接的部份 ，以形成多片體厚度的構架，但是一般人可瞭解，本發明 -26- *200940203 可使用其他的結構和修飾。 參考圖13D-13E，其顯示本發明各種態樣的另一構架 。片體材料272’類似於片體材料272。片體材料包括彎曲 線279’。彎曲線可由複數有利彎曲的構造所界定。在各種 實施例中，準備片體材料和彎曲線，以形成類似於上述重 疊構造277的重疊構造27 7’。彎曲線將片體材料分隔成第 —部份279’和第二部份281’。第一部份和第二部份的每一 Q 者包括趨近彎曲線的弧形部份305’。第一部份包括由預成 形的彎曲3 03’所界定之預成形彎曲角凸緣2 82’。角凸緣從 弧形部份的相反端延伸。當沿著彎曲線彎曲片體材料時， 第一部份和第二部份彼此接近，直到各弧形部份彼此嚙合 或接觸爲止。各弧形部份的嚙合，當作流體性密封彎曲線 之用。 參考圖13F-13G，其顯示本發明各種態樣的另一構架 。片體材料272”類似於片體材料272和272’。片體材料 〇 包括彎曲線279”。不是實質直的預形成彎曲角凸緣，材料 片體包括弧形凸緣部份，其從預形成彎曲弧形3 06”延伸。 當彎曲材料片體時，片體的截面形成重疊的構造’且弧形 凸圓形成滑順或圓的角隅。愈滑順的角隅進一步提供對食 物碎肩、油脂、和類似者的密封。雖然各弧形凸緣部份是 滑順的弧形且彼此鏡射對稱，但是本發明可使用其他的形 狀和結構。 參考圖13H-13K，各種其他構架結構都在本發明的範 圍內。可準備片體材料，使得在彎曲之後，重疊的構造位 -27- 200940203 在已彎曲的構造內或在內部容積的內側（例如圖13J所示 )。重疊構造也可具有各種形狀和結構。參考圖13D-13E 和26K，重疊構造可具有鉤狀。已經發現此形狀減少微波 能量和輻射的洩漏。 依據不同的應用，彎曲線的處理可不同。可進行修飾 ，以增加所產生之構造徑度和剛性，例如在彎曲之後將片 體熔接或固定在一起。 其他的應用可要求防止流體滲漏（fluid tight)的構 造。在此等應用中，可希望提供彈性且能抵抗流體的材料 ，例如在第一和第二部份內部的橡膠，使得在兩者間的接 觸形成緊密封。一些應用可能不要求彎曲線的緊密封，在 此情況中’片體可只局部彎曲，且第一和第二部份不彼此 緊靠。「密封」並非意指完美地防止空氣和流體滲漏的密 封’而是意指關閉大部份的可見光，且有待所應用之領域 的內容進一步的定義。例如密封可要求接觸點提供構造的 強度、或限制食物和油脂卡在角隅和彎曲線之內部的風險 。在防止流體滲漏的情況中，「密封」意指將特定流體密 封在外。 一般人可瞭解，在產生三維構造的其他態樣中，可修 飾和利用重疊構造。例如可由具有重疊構造的片體材料形 成底部249。可建構重叠構造成凸緣，以嚙合殻體增加穩 定性、或嚙合安裝座267。藉由對齊片體材料的一部份而 不須彎曲線，便可形成重疊構造。例如圖13H所示，在分 離的片體上預形成的彎曲角凸緣，可彼此對齊而不使用彎 *200940203 曲線。可修飾本發明所示和所述的各種態樣，以達成較低 成本、和/或增加效能和可變通性。 相較於習知具有多個重疊彎折之片體材料，本發明提 供多項優點。如圖13A-13G和圖14所示，重疊構造將彎 曲線279隔離在距離爐之內部容積288遙遠的位置。重疊 構造也提供彎折技術的好處，同時保持爐隔室之被密封的 角隅。因此，即使未施加塗層或其他處理至彎曲線，該等 〇 好處保持相對於爐之功能性零件，特別是爐隔室的內部烹 飪表面。 上述的彎折構造除了可利用在器具和烹飪灶以外，也 可使用在其他各種應用中。例如可修飾構造供應用於包括 (但不限於）電子組件底板、機動車輛組件和底板、運輸 組件和底板、營建組件和底板、和其他等的形成。 現在將槪要描述製造爐隔室和240和殼體239的方法 。不詳細描述例示烹飪灶的完整製造，例如不描述爐頂部 © 次組合體的製造和組合至烹飪灶。反而，下列的討論意欲 向熟悉該項技藝者例示本發明的構造和方法，及其和製造 整個產品之其他技術如何相關聯。 如上所述，可由單一片體材料沿著上述複數彎曲線彎 折而形成爐本體。雖然顯示成分離的面板，但是殼體可同 樣地由彎折的片體材料形成。因爲三維構造（包括爐隔室 )可由一或多個已彎折的片體材料形成，所以在彎折之前 可以先處理片體。例如在組合之前，可施加非附著塗層至 片體。對照涉及許多運動零件、複雜系統、和附接各種組 -29- 200940203 件的習知組合製程，形成本發明構造的方法簡單且利用較 少零件及運動機器。因此表面較不會出現刻痕、凹陷、和 碎裂。 殼體239提供灶230的芯部骨架構造。殻體包括背部 面板構造29 1和側面板293。側面板除了提供所需的剛性 以外，也形成構造的裝飾外部。 殻體容置或包覆爐本體247 (示於圖2)。在各種實 施例中，爐本體設置在殼體內，使得彎曲線2 79位在角隅 附近（圖13C)。殻體設置在殼體角隅之鉤內和剛性角凸 緣內，使爐本體和殼體相互補強。以此方式，嚙合或鎖固 殻體和內部構造，使得邊對邊的運動施加壓力在材料本體 和爐隔室上。因此，爐隔室和殼體的結構當作交互支撐， 以對系統提供附加的剛性。 參考圖15_ 16，背部291具有大致矩形的剖面，且提 供灶之工作隔室後端和抵靠背部而設的壁之間的間距。電 性系統、瓦斯或電性連接、和其他組件使用背部面板所提 供的空間。 背部面板構造291當作殻體的骨幹。背部面板包括複 數薄壁，其中空截面。背部構造包括各種凸緣、角隅、凸 片、和類似者’以增加剛性並提供使用內部容積。在各種 實施例中’背部面板構造的每一側包括支柱295，該等支 柱由薄壁區段296所界定之中空容積形成。 背部面板構造由片體材料沿著複數彎曲線彎折而成， 以形成各種壁區段。設置和建構彎曲線，使得被彎曲的片 -30- 200940203 體材料界定預先決定之支柱29 5的截面。使用上述參考專 利案所描述的精密彎曲技術，可準備片體材料供精密彎曲 ，以精密地控制構造的最後形狀。可製備片體材料使其具 有彎曲控制位移（例如狹縫或槽），以幫助彎曲和控制彎 曲。以此方式，可精密地形成背部面板，以匹配灶構造 23 0的其餘部份並執行其所需的功能。 形成貝部面板構造的片體材料包括至少一條彎曲線， φ 其界定向外彎折的凸片部份（例如圖15)。向外彎折的凸 片部份形成在被彎曲構造的其中一壁內，使得其向下彎折 進入支柱之預定截面或內部容積內。凸片具有和支柱之預 定截面互補的周圍形狀。 當凸片被彎折進入支柱內部時，至少一側嚙合或變成 趨近立即鄰接的壁。因此，凸片嵌套在支柱內，且藉由提 供阻擋或抵抗壁的運動而界定部份截面。當力量傳輸經過 灶時，支柱構造有運動的傾向，但是會被凸片所限制。支 〇 柱的任何運動都會施加壓（縮）力在片體上，片體會施加 相反的力，因此可限制運動。以此方式’凸片當作支柱的 截面支撐。如同熟悉該項技藝人士從上文可瞭解者，藉由 嚙合至少一個壁，凸片可界定支柱壁構造的形狀，且藉由 嚙合至少二個壁，凸片可支撐構造。在各種實施例中，建 構凸片成「火柴盒」的壁構造。 如同熟悉該項技藝者所瞭解的，可修飾凸片和支柱構 造。可設計凸片的尺寸對應於支柱截面的尺寸，以產生干 涉配合，藉此使凸片緊靠著內部壁面。在另一實施例中， -31 - 200940203 可將凸片設置在支柱內側，使得全部或只有一部份的周圍 鄰接著壁。也可建構凸片使其嚙合或固定至支柱的其中一 壁。例如可藉由將凸片扣合（snap )進入各壁所界定的空 間內而保持著壁。也可使用其他無固定件的結構、或包括 (但不限於）鉤、槽內凸片（tab-in-slot )、扣合件、黏 劑、鉚釘、和類似者的固定件，而將凸片固定至壁。雖然 所示的凸片向下彎折至和支柱壁實質地正交的角，但是可 依據支柱的結構以各種方式向下彎折凸片。 可設置類似的凸片和凸緣穿過灶構造230。可在背部 面板構造291內設置向外彎折的凸片，以將構造固定至爐 隔室和/或殼體側面板。例如可建構凸片以在側面板上提 供給固定件用的附接點。也可提供凸片以將鄰接的面板和 組件固定在一起，以提昇構造剛性或幫助組合組件。 可由許多種製程形成三維構造。參考圖17A-17J，在 各種實施例中，由整捲貯存的材料257,形成三維構造。展 開整捲的材料成爲長片體材料2 72b。 在各種實施例中，於將片體2 72b盤繞成捲之前，可 先處理片體272b。例如可以塗層（譬如非附著塗層）處理 材料。可在製程中的各階段、或在三維構造的最後組合（ 亦即在最後步驟期間）以後，處理片體。 將片體饋給經過機器，建構該機器以在饋給片體時， 在片體材料內形成特徵。該等特徵包括幫助彎曲的構造 2 74b。依據應用和製造的要求，可片體內形成其他的特徵 284。可在片體材料內形成例如安裝構造、孔、凸片、架 200940203 子、和類似者。可藉由以矛沖壓、沖孔、抽引製程、和類 似者來形成特徵。當饋給片體材料時，可在一或多個步驟 中，在片體材料的橫方向中形成特徵。也可將組件就地附 接至片體。 當將整捲貯存的材料展開時，可增加其他特徵至片體 上游。此等特徵包括（但不限於）功能性組件和次組合體 。可使用黏劑、熔接、固定件、和類似的製程附加該等特 ❹ 徵。 在片體272b內形成幫助彎曲構造以後，片體可經歷 輥壓形成上或下線。參考圖13A中順序（A)至（E)， 片體可遭受撞擊，以沿著縱向的彎曲線產生連續的彎曲。 可逐漸地或階段性地進行彎曲。可沿著彎曲線連續地或以 平行的方式執行彎曲。也可以任何次序執行輥壓成形，以 形成在片體內的特徵。 製程包括在形成一或更多特徵以前或以後，由整捲貯 © 存的材料提供片體材料。片體可爲粗切割，然後再最後加 工。也可精密地切割，藉此在單一步驟中產生已加工的成 品。 由上述可瞭解，上述的製程允許快速且有效率的處理 。可將整捲貯存的材料饋給經過簡單且已修飾的組合體， 以便用較少數目的步驟形成片體產品310，。如圖17B-17C 所示’在切割之前可在生產線上執行一些彎曲。然後可藉 由沿著彎曲線進一步彎曲產品，而形成結果產品。因此， 可用一些簡單的工作站將片體製備和彎曲成三維構造。 -33- 200940203 翻到圖13-17，可由複數片體分離地製造各種組件和 次組合體。在各種實施例中’形成面板312 ’用於插入結果 的三維構造。可建構面板312’類似於上述的底部249’使 其可調整地設置在待形成之器具隔室內。面板包括外唇部 或凸緣286，其繞著面板的周圍延伸。一般人可瞭解，也 可將凸緣形成類似於上述的彎折構造。片體272b包括對 應的唇部特徵88，可藉由上述製程將唇部特徵形成在片體 內。 ❹ 當沿著彎曲線彎曲片體時，重疊構造2 77b形成在角 隅（示於圖17F)。片體進一步包覆面板312’。藉由將唇 部314’固定至在變成內壁之對應唇部316’，而將面板固定 在已彎曲之構造的內側（顯示在圖17F)。已彎曲的構造 內可設置許多的面板，以修飾待成形之三維構造的佈局和 結構。 參考圖1 71-1 7J，藉由沿著彎曲線彎曲片體產品，可 形成三維構造。然後可增加額外的構造特徵，並可完成該 Q 構造。在各種實施例中，將安裝拖架附加至已彎曲的構造 ，以支撐構造並提供給門用的安裝表面。在最後加工期間 ，進一步附加腳、標籤、絕緣、導線、和其他構造特徵及 組合體。 一般人可瞭解，上述的製程可依據不同的應用而做修 飾。也可改變各步驟的順序。形成在片體內之構造特徵元 件的方式可改變、和/或以不同的製程來執行。藉由改變 整捲貯存材料的寬度和/或將片體切斷、切成長條、衝孔 -34- 200940203 的形狀、位置、和時機，也可容易地修飾待形成之三維產 品的尺寸。其他的修飾和變化都可認爲是在本發明的範圍 內。 現在輪到圖1 8，大致以3 0代表之例示的已彎折三維 構造，顯示本發明的一些態樣。可修飾例示的構造30，用 於和上述的例示灶器具整合，或做爲分離的器具。在一些 態樣中，構造30類似於上述的構造23 0。 Φ 在一例示的實施例中，三維構造30是具有鉸接蓋的 殻體構造，該殼體構造例如器具（諸如爐、洗碗機、洗衣 機、或乾衣機）、容器（諸如保險箱、工具箱、或櫥櫃） 、或機殼（enclosure )。 例示的爐通常由二維片體構件所形成，其中一些可爲 預先組合的組件，且另一些可在現場組合。圖21A至圖 21P例示形成本發明各種態樣之三維構造的例示方法。對 照圖17所例示之上述形成構造23 0的製程，形成例示構 〇 造30的方法允許成扁平狀運輸零件並在遠地組合。下述 的製程也需要零件的較大互聯關係和在製程中更多手動勞 力。但是一般人可瞭解，本發明的製程可依據不同的應用 而做修飾。 下文將更詳細描述之選擇性工作台32，提供穩定的平 台供彎折和形成三維構造的各種子零件。在例示的實施例 中，工作台具有在三方向的延伸部，以提供用於形成爐之 側面的工作表面。因爲爐的前面包括爐的門和儀錶等，這 些組件可在其他地方預先組合當作次組合體’並在組合期 -35- 200940203 間固定至殻體構造。但是也可使用類似於本文所述的方法 來組合這些組件。事實上，藉由彎曲依據本文所述原則而 製備之片體材料和使用例如上述‘934和‘216申請案所揭露 之方法’可形成爐之大部份（如果沒有全部）構造組件和 本體》 參考圖18’呈內部爐腔室之例示三維構造，包括由— 或更多二維片體材料35所形成之大致盒狀內部芯構造33 。在例示的實施例中，內部構造33是由五個片體所形成 ’但是一般人可瞭解，內部構造可由一、二、三' 或更多 片體材料來形成。如同將於下文描述者，每一片體材料可 爲不具彎曲線或可具有一或更多彎曲線37的剛性構件， 以利彎曲成三維構造而形成內部構造。在另一實施例中， 內部構造可爲整合地預成形三維構造。 內部構造設置在殼體39內，其也是由一或更多二維 片體材料40彎折成三維構造而形成。也可建構片體材料 4〇供以類似於上述片體而沿著複數彎曲線42彎曲。複數 彎曲線進一步界定殻體的側面或面板44、和輪廓。在例示 的實施例中，每一側面44形成殻體構造的大致平坦面（ 例如見圖24)，但是一般人可瞭解，也可界定其他形狀和 構造。例如可沖壓片體使其具有肋、和/或其他構造特徵 、和/或裝飾細節，其可強化、有利組合體、和/或改善構 造整合性或美觀。 內部構造和殼體的彎曲線包括複數定位構造46’以便 利和指定一個外側面相對於另一個外側面沿著一或更多彎 -36- *200940203 曲線彎曲的位置。在一個例示的實施例中，建構在第一面 板部份47a上之至少一個定位構造46a，以嵌套在第二面 板部份49b上之另一個定位構造46a內，使得面板部份沿 著殻體的外側躺平。 在一個實施例中，定位構造被形成在殼體、和內部構 造和/或任何數目之其他組件的一或兩者上，以呈扁平狀 傳輸，然後被彎折成三維構造；亦即成大致二維的狀態， φ 然後被彎折成三維構造。在例示的實施例中，複數彎曲誘 導構造被形成在片體35和40的厚度方向中。 在例示的實施例中，形成殼體的片體材料包括沿著個 別彎曲線42的周圍凸緣部份53，其沿著片體材料的面板 部份54延伸。彎曲線沿著面板部份的周圍延伸，以形成 周圍凸緣部份。如圖21G最清楚地顯示，周圍凸緣部份包 括沿著面板部份54的外部垂片（tab or flap)。在例示的 實施例中，周圍凸緣部份從界定面板之外部周圍的彎曲線 〇 延伸。在彎曲製程期間，在面板部份被彎折以前，周圍凸 緣被沿著個別彎曲線彎曲。 周圍凸緣用於數個目的。如圖21M至210所示，周 圍邊緣提供一部份片體，以在繞著內部構造33周圍彎折 時’和殼體39耦合在一起。各周圍凸緣也沿著殼體的變 緣51彼此重疊，使得殻體的邊緣和角隅具有多層片體。 例如當周圍凸緣和個別面板部份54彎折超過殻體之另一 面板側面54b時’周圍凸緣會重疊此鄰接面板54b的一部 份’並產生一種二片體厚的架構（例如見圖23A)。因此 -37- 200940203 每一周圍凸緣部份和個別面板覆蓋另一面板的彎曲線或周 圍凸緣，而形成雙層厚度的架構。構造的邊緣和角隅通常 承載構造的重要負載，因此上述結構允許額外的材料厚度 在構造的主要負載承受部份。以此方式，例示的殻體構造 具有的骨架架構是：沿著邊緣和角隅增加材料厚度和強， 但不增加整體構造的總厚度。 在圖23A所示的例示實施例中，片體材料包括第一周 圍凸緣部份53a和第二周圍凸緣部份53b。第一周圍凸緣 部份53a沿著第一彎曲線重疊片體材料的第一面板部份 54a。第二周圍凸緣部份53b沿著第二彎曲線重疊片體材 料的第二面板部份5 4b。因此周圍凸緣和面板形成的架構 56沿著殼體的邊緣具有額外的厚度，用於額外的支撐。在 例示的實施例中，沿著三維構造的周圍具有二片體厚度的 架構，因此界定承受負載的架構。 再參考圖21H至21L，內部構造可包括一或更多支撐 凸緣58，其從該內部構造的周圍向外延伸，且建構該等支 撐凸緣以嚙合殻體。將內部構造置於殼體內呈包覆的配置 ，如圖21L至圖21P、和圖23A至圖24所示。每一支撐 凸緣向殼體的個別彎曲線42延伸。在內部構造33包括彎 曲線的情況中，支撐凸緣從內部構造向殼體39的架構56 延伸。 輪到圖21-23，內部構造包括沿著內部構造之周圍而 形成的內部骨架構造60。內部骨架構造是由內部邊緣61 、內部構造凸緣58、和內部構造的角隅組合而形成。內部 -38- .200940203 構造邊緣和凸緣沿著內部構造的周圍在角隅 一起。在例示的內部構造中，各凸緣彼此重 從個別的內部構造邊緣向殼體的彎曲線延伸 重疊結構，重疊凸緣彼此固定至內部構造或 因此，凸緣支撐內部骨架結構60防止運動 藉由凸緣支撐內部構造而呈「火柴盒」型式 〇 〇 此外，當內部構造被設置在殼體的內側

再參考圖13，可以類似的方式將已彎曲 一樣地裝設在殻體的內側。如同由上文描述 依據不同的應用而修飾殼體和內部構造凸緣 於待形成之三維構造，內部構造可具有任何 可改變凸緣的數目和結構。例如內部構造可 彎曲線或邊緣之內側上的球狀或曲線部份。 或頂點結合在 疊。每一凸緣 。依據特殊的 殻體的面板。 。以此方式， ’且反之亦然 時’內部骨架 每一凸緣58 鉤部63是由 端從彎曲線對 殼體內的彎曲

緣的一部份。當另一組件欲被設置在角隅或邊緣、或者一 些其他設計限制條件要求移動凸緣安裝點時，可能希望有 上述結構。 再參考圖21-23，在一實施例中，每一支撐凸緣包括 在其外部邊緣67上的固定構造65，以將凸緣固定至殼體 ，藉此將內部構造固定至殼體，並維持凸緣和各別彎曲線 之間的嚙合（例如見圖27)。每一內部構造支撐凸緣的固 定構造合倂殻體39的個別定位構造，以將內部構造33支 撐在殻體內。 在一實施例中，固定構造具有垂片或槽結構。固定構 造65包括沿著殼體之個別彎曲線42或鉤63的垂片68和 個別的槽或孔70。固定構造65較佳是由個別片體材料整 體成形，如同例示實施例的情況。在彎折期間或之後’垂 片可插入孔內，藉此將內部構造的的個別支撐凸緣嚙合至 殻體的一部份。如圖所示’設置有許多固定構造’以將內 部構造的每一橫向角隅和殻體的個別角隅嚙合，而將內部 構造在空間上固定至殼體。 在此實施例中，每一支撐凸緣不需分離的固定構造便 可固定至殼體。反而，在組合三維構造期間，當垂片68 嚙合對應的孔70時’凸緣58鎖入彎曲線的鉤63。在另一 .200940203 實施例中，凸緣可一點都不延伸進入個別彎曲線的鉤內’ 和/或凸緣可包括中間構造以嚙合殻體。 如上所述，凸緣可被固定至殼體或內部構造其中之一 ，或者凸緣可被以殼體或內部構造其中之一形成。在另一 例中，凸緣可自由地設置在內部構造和殼體之間。例如殻 體或內部構造其中之一可使用對齊構造，以在彎曲殼體期 間對齊凸緣。一旦殼體被形成，凸緣可被保持在個別彎曲 @ 線之鉤內定位。 也可使用其他的固定構造，包括（但不限於）上述 ‘440號申請案所描述者。此等固定構造包括（但不限於） 連結支座（tie mount )、扣件、螺栓等。 依據不同的應用，可改變構造、尺寸、和結構。在一 實施例中，至少一凸緣從內部構造成銳角延伸至殼體，該 銳角是與內部構造33之內部側面所界定的平面夾角。在 一實施例中，至少一凸緣以離該平面約45度延伸。其他 G 的結構包括（但不限於）設計凸緣58的尺寸和形狀用於 特殊的應用。例如，凸緣的決定尺寸可用於提供阻止殻體 之彎曲線的運動，或可建構凸緣以提供彈性力或「給予（ give )」至整個三維構造。因爲每一凸緣有效率地引導或 限制個別彎曲線的運動，所以可以各種方式建構凸緣，&amp; 控制三維構造的整體剛性和運動。再者，可建構一個以上 的凸緣（特別是在內部構造之相對角隅上的凸緣）一起^ 作，以影響和控制三維構造的物理特徵。 當殻體39包覆在內部構造33周圍時，內部構造賦予 -41 - 200940203 殻體強度和剛性，反之亦然。在一實施例中，殼體是鬆弛 地形成構造，其具有獨立地最小強度。內部構造和凸緣賦 予殻體構造和整個三維構造強度。特別地，凸緣固定和支 撐殼體的個別彎曲線。在一實施例中，殼體和內部構造彼 此獨立時，都不具重要強度。一般人可瞭解，可以各種方 式配置內部構造33、凸緣58、和殻體39，以增加結果三 維構造的剛性和強度。在例示的實施例中，內部構造和凸 緣在殼體內形成一種交叉支撐，藉此，形成爐盒的內部構 造相互補強爐殼體。 類似於殼體，可由至少一內部片體材料3 5b (包括內

formed by bending a single piece of material. The sheet material is prepared for bending and bending along the bending line 2 79 during the process of manufacturing the cooking hob. The sheet may be a single piece of sheet material, or a plurality of sheets joined together. In many aspects, the sheet material of the present invention is similar to those disclosed in the following patents: '259, '349, '426, '449, '450 patent, and US 10/821818 ( US Patent Application Publication No. 2005/0005670, U.S. Patent Application No. 7,032,426, U.S. Patent No. 7,263,869, U.S. Patent No. 7,225,211, U.S. Patent No. US Pat.

Patent application, US 60/854846 and No. US provisional patent application. The entire contents of these patents and patent applications are incorporated herein by reference for all purposes. Other advantageous curved configurations that are conceivable are within the scope of the invention. These structures are typically able to find locations and position individual bend lines during bending. For example, such configurations can be used to determine where bending occurs in the sheet material, and also to position the various portions of the sheet material, including edges, faces, and the like, during bending. The construction can be further used to facilitate the use of minimal tools and forces to bend the sheet of material. Some applications may require surfaces with increased reflectivity, reduced build up of grease, and other features. Coatings and laminates have been found to provide an effective means of altering the material properties of the furnace compartment. However, when coatings, laminates, and the like, together with the bent sheets prepared by the above technique, there is a tendency to become shards or peel off. The sheet material is subjected to bending, twisting, stretching&apos; such steps make it difficult to coat efficiently in the area of the curved line. With particular reference to Figures 7, 13-14, the sheet material 272 can include configurations that improve the use of bending techniques with surface and material preparation. Preparing the sheet material -24- *200940203 has a plurality of advantageously curved configurations 274' which define a bend line 275. The advantageously curved configuration 2 74 can be slits, grooves, displacements, holes, and the like. In various embodiments, the sheet material and the bend line are prepared to form an overlap configuration 2 77 that seals the bend line at a remote location from the interior of the furnace. The bending line divides the sheet material into a first portion 279 and a second portion 281. Each of the first portion and the second portion includes a pre-formed angled flange 282 that defines a pre-formed bend 303'. The corner flanges extend at an angle from one end facing the bending line such that the sheet shape on each side of the curved line forms an angle. During bending, the first portion and the second portion are close to each other until the two portions abut each other. "Abut" means that the first part and the second part exert a contact force on the other at one point. Therefore, the first portion overlaps the other, thereby forming a plurality of frame thickness frames. As used herein, "overlapping configuration" means by bending a sheet of material having a pre-formed angular flange until the first portion and the second portion abut each other. The sheets may also be formed and bent such that the respective hard preformed bends G 303' are adjacent to each other. In various embodiments, the sheet material is constructed such that the ends of the sheets are slightly curved through a point at which the pre-formed bends are in contact. In various embodiments, each pre-formed bend is slightly less than 135 degrees. The sheet material is bent along the bend line until each of the pre-formed bends contacts 'slightly greater than 90 degrees. Then, the sheet is further bent until a corner of 90 degrees is formed, and a pressure is applied to the contact point between each of the pre-formed curved corners to slightly preload the sheet. In this way, pressure is applied to increase the seal of the overlapping portions of the sheets. Although described as "pre-formed", it is generally understood that angles can be formed before or after other processes in the text of -25-200940203. For example, the flange may be formed from a sheet having a flat quality before or after bending along the curved line. As used herein, &quot;preformed bend&quot; means a rigid and fixed bend. For example, the sheet material 272 is similar to an angle bracket that is joined along a curved line. The processing of the material allows the material to be permanently altered and retained in shape by processing the material or using other conventional techniques to effect a rigid bend angle to form each preformed corner. From another point of view, the pre-formed bending and bending lines are different because the bending lines act like hinges and the pre-formed curves have relative stiffness. In effect, the material is processed to form a pre-formed bend that is intended to change the shape of the sheet and prevent bounce. While the above-described bending techniques promote bending, such techniques do not prevent bounce back to their original shape without additional features such as snap fit and angle locking. In contrast, conventional techniques of fixing the angle and shape more like the original shape of the sheet are used to form the pre-formed bend. The energy required to change the bending angle is similar to the energy required to bend any other part of the sheet. As shown in Figures 13B-13C, the aforementioned architecture forms a similar backslash joint. In the bent position, the first portion and the second portion are substantially flat with each other. The preformed curved corner flange extends from the first and second portions at a pre-formed or predetermined bend angle. The pre-formed bend angle defines the base of the curved corner flange and the base of each portion can abut one another. The curved line is at the opposite end of the first and second portions from the pre-formed bend angle. Therefore, the bending line is located in an engagement region away from the pre-formed bending angle. Although the construction has been described so far as to form portions of the sheets adjacent to each other to form a multi-piece thickness frame, it is generally understood that other structures and modifications can be used in the present invention -26-*200940203. Referring to Figures 13D-13E, another architecture of various aspects of the present invention is shown. The sheet material 272' is similar to the sheet material 272. The sheet material includes a curved line 279'. The bend line can be defined by a plurality of advantageously curved configurations. In various embodiments, the sheet material and the curved lines are prepared to form an overlapping configuration 27 7' similar to the overlapping configuration 277 described above. The curved line divides the sheet material into a first portion 279' and a second portion 281'. Each of the first and second portions includes an arcuate portion 305' that approximates the curved line. The first portion includes a preformed curved corner flange 2 82' defined by a pre-formed bend 3 03'. The corner flange extends from the opposite end of the curved portion. When the sheet material is bent along the bending line, the first portion and the second portion are close to each other until the arcuate portions are engaged or contacted with each other. The engagement of the arcuate portions serves as a fluid tight bend line. Referring to Figures 13F-13G, another architecture of various aspects of the present invention is shown. The sheet material 272" is similar to the sheet materials 272 and 272'. The sheet material 〇 includes a curved line 279". Not a substantially straight pre-formed curved corner flange, the sheet of material comprising a curved flange portion extending from the pre-formed curved arc 306". When the sheet of material is bent, the cross-section of the sheet forms an overlapping configuration' And the arcuate convex circles form a smooth or rounded corner. The smoother corners further provide a seal to the food shoulders, grease, and the like. Although the curved flange portions are smooth and curved The mirrors are symmetrical to each other, but other shapes and configurations can be used with the present invention. With reference to Figures 13H-13K, various other frame structures are within the scope of the present invention. The sheet material can be prepared such that after bending, the overlapping configuration bits - 27- 200940203 Within the curved configuration or inside the internal volume (such as shown in Figure 13J). The overlapping configuration can also have a variety of shapes and configurations. Referring to Figures 13D-13E and 26K, the overlapping configuration can have a hook shape. This shape reduces leakage of microwave energy and radiation. Depending on the application, the bending line can be treated differently. Modifications can be made to increase the resulting structural diameter and rigidity, such as melting the sheet after bending. Attached or secured together.Other applications may require a fluid tight-tight construction. In such applications, it may be desirable to provide a resilient and fluid-resistant material, such as within the first and second portions. The rubber causes a tight seal between the two. Some applications may not require a tight seal of the bend line, in which case the 'sheet may only be partially bent and the first and second portions do not abut each other." "Sealing" does not mean a seal that perfectly prevents leakage of air and fluids, but rather means that most of the visible light is turned off, and the content of the field to be applied is further defined. For example, sealing may require the contact points to provide strength to the construction or to limit the risk of food and grease sticking inside the corners and bend lines. In the case of preventing fluid leakage, "sealing" means sealing a particular fluid out. It is generally understood that in other aspects that create a three-dimensional configuration, the overlapping construction can be modified and utilized. The bottom 249 can be formed, for example, from a sheet material having an overlapping configuration. The structurable overlap is configured as a flange to engage the housing to increase stability or to engage the mount 267. The overlapping configuration can be formed by aligning a portion of the sheet material without bending the wire. For example, as shown in Fig. 13H, the curved corner flanges preformed on the separated sheets can be aligned with each other without using the curved *200940203 curve. The various aspects shown and described herein can be modified to achieve lower cost, and/or increased performance and flexibility. The present invention provides a number of advantages over conventional sheet materials having a plurality of overlapping bends. As shown in Figures 13A-13G and Figure 14, the overlapping configuration isolates the curved curve 279 from a location remote from the internal volume 288 of the furnace. The overlapping configuration also provides the benefits of the bending technique while maintaining the sealed corners of the furnace compartment. Thus, even if no coating or other treatment is applied to the bend line, the benefits are maintained relative to the functional parts of the furnace, particularly the internal cooking surface of the furnace compartment. The above-described bent structure can be used in various other applications in addition to appliances and cooking ranges. For example, the configurable construction is provided for the formation of, but not limited to, electronic component backplanes, motor vehicle components and backplanes, transport components and backplanes, building components and backplanes, and the like. A method of manufacturing the furnace compartment and 240 and the casing 239 will now be briefly described. The complete manufacture of the cooking hob is not described in detail, for example, the manufacture and assembly of the top of the furnace © sub-combination to the cooking hob is not described. Instead, the following discussion is intended to exemplify the construction and method of the present invention and how it relates to other techniques for making the entire product. As described above, the furnace body can be formed by bending a single sheet material along the above-described plurality of bending lines. Although shown as a separate panel, the housing can be similarly formed from a bent sheet material. Because the three-dimensional construction (including the furnace compartment) can be formed from one or more bent sheet materials, the sheet can be processed prior to bending. For example, a non-adhesive coating can be applied to the sheet prior to combining. The method of constructing the present invention is simple and utilizes fewer parts and moving machines, as opposed to many moving parts, complex systems, and conventional combination processes that attach various sets of -29-200940203 pieces. Therefore, the surface is less likely to be scored, sunken, and chipped. The housing 239 provides a core skeleton configuration of the cooktop 230. The housing includes a back panel construction 29 1 and a side panel 293. In addition to providing the required rigidity, the side panels also form a decorative exterior of the construction. The housing houses or encloses the furnace body 247 (shown in Figure 2). In various embodiments, the furnace body is disposed within the housing such that the bend line 2 79 is positioned adjacent the corner (Fig. 13C). The housing is disposed within the hook of the housing corner and within the rigid corner flange to complement the furnace body and the housing. In this manner, the housing and internal configuration are engaged or locked such that the edge-to-side movement exerts pressure on the material body and the furnace compartment. Thus, the structure of the furnace compartment and the housing acts as an interactive support to provide additional rigidity to the system. Referring to Fig. 15_16, the back portion 291 has a substantially rectangular cross section and provides a space between the rear end of the working compartment of the cooking chamber and the wall provided against the backrest portion. Electrical systems, gas or electrical connections, and other components use the space provided by the back panel. The back panel construction 291 serves as the backbone of the housing. The back panel includes a plurality of thin walls with an empty cross section. The back construction includes various flanges, corners, tabs, and the like to increase rigidity and provide for the use of internal volume. In various embodiments, each side of the 'back panel construction includes a post 295 formed by a hollow volume defined by a thin wall section 296. The back panel construction is formed by bending the sheet material along a plurality of curved lines to form various wall segments. The bend line is set and constructed such that the bent sheet -30-200940203 body material defines a cross section of the predetermined struts 295. Using the precision bending technique described in the above referenced patent, the sheet material can be prepared for precision bending to precisely control the final shape of the construction. The sheet material can be prepared to have a bending control displacement (such as a slit or groove) to aid in bending and controlling bending. In this way, the back panel can be precisely formed to match the rest of the stove construction 230 and perform its desired function. The sheet material forming the shell panel construction includes at least one bend line, φ which defines an outwardly bent tab portion (e.g., Figure 15). The outwardly bent tab portion is formed in one of the walls of the curved configuration such that it is bent downward into a predetermined section or interior volume of the strut. The tab has a peripheral shape that is complementary to a predetermined section of the post. When the tab is bent into the interior of the post, at least one of the sides engages or becomes a wall that abuts immediately. Thus, the tabs are nested within the struts and define a partial section by providing a barrier or resistance to movement of the wall. When the force is transmitted through the stove, the pillar structure has a tendency to move, but is limited by the tab. Any movement of the struts will exert a compressive (reducing) force on the slab, which will exert opposing forces, thus limiting movement. In this way the tab is supported as a section of the strut. As will be appreciated by those skilled in the art, by engaging at least one wall, the tabs can define the shape of the strut wall configuration and the tabs can support the configuration by engaging at least two walls. In various embodiments, the tabs are constructed as a "matchbox" wall construction. The tabs and struts can be modified as would be appreciated by those skilled in the art. The dimensions of the slatable tabs correspond to the dimensions of the cross-section of the strut to create a interference fit whereby the tabs abut against the inner wall. In another embodiment, -31 - 200940203 may be provided with tabs on the inside of the post such that all or only a portion of the circumference abuts the wall. Tabs may also be constructed to engage or be secured to one of the walls of the post. The wall can be held, for example, by snapping the tab into the space defined by the walls. Other non-fixed structures, or including, but not limited to, hooks, tab-in-slots, fasteners, adhesives, rivets, and the like, may be used to The piece is fixed to the wall. Although the tabs shown are bent down to an angle substantially orthogonal to the pillar walls, the tabs can be bent downward in various ways depending on the structure of the strut. Similar tabs and flanges can be provided through the cooktop construction 230. An outwardly bent tab may be provided in the back panel construction 291 to secure the structure to the furnace compartment and/or the housing side panel. For example, a tab may be constructed to provide an attachment point for the fixture on the side panel. Tabs may also be provided to secure adjacent panels and components together to enhance structural rigidity or to aid in assembly. Three-dimensional construction can be formed by a variety of processes. Referring to Figures 17A-17J, in various embodiments, a three-dimensional configuration is formed from the entire volume of stored material 257. The material of the entire roll is expanded into a long piece of material 2 72b. In various embodiments, the sheet 272b may be processed prior to coiling the sheet 2 72b into a roll. For example, the material can be treated with a coating such as a non-adhesive coating. The wafer can be processed at various stages in the process, or after the final combination of the three-dimensional construction (i.e., during the final step). The sheet is fed through a machine that is constructed to form features within the sheet material as it is fed to the sheet. These features include a configuration 2 74b that aids in bending. Other features can be formed in the body depending on the application and manufacturing requirements. For example, mounting configurations, holes, tabs, frames 200940203, and the like can be formed within the sheet material. Features can be formed by stamping, punching, drawing processes, and the like with spears. When the sheet material is fed, features may be formed in the transverse direction of the sheet material in one or more steps. It is also possible to attach the component to the sheet in situ. When the entire roll of stored material is unfolded, additional features can be added to the upstream of the sheet. Such features include, but are not limited to, functional components and sub-combinations. These features can be attached using adhesives, welds, fasteners, and the like. After forming the help bending configuration in the sheet body 272b, the sheet body may undergo roll forming upper or lower lines. Referring to the sequences (A) to (E) in Fig. 13A, the sheet may be subjected to impact to cause continuous bending along the longitudinal bending line. The bending can be performed gradually or in stages. The bending can be performed continuously or in a parallel manner along the bending line. Roll forming can also be performed in any order to form features within the sheet. The process includes providing the sheet material from the entire stock of material stored before or after the formation of one or more features. The sheet can be rough cut and then finished. It can also be cut with precision to produce a finished product in a single step. As can be understood from the above, the above process allows for fast and efficient processing. The entire roll of stored material can be fed through a simple and modified assembly to form the wafer product 310 in a reduced number of steps. As shown in Figures 17B-17C, some bending can be performed on the production line prior to cutting. The resulting product can then be formed by further bending the product along the bend line. Therefore, the wafer can be prepared and bent into a three-dimensional configuration using some simple workstations. -33- 200940203 Turning to Figures 13-17, various components and sub-assemblies can be fabricated separately from a plurality of sheets. The 'form panel 312' is used in various embodiments for the insertion of the resulting three-dimensional configuration. The configurable panel 312' is similar to the bottom 249' described above such that it is adjustably disposed within the appliance compartment to be formed. The panel includes an outer lip or flange 286 that extends around the perimeter of the panel. It will be appreciated by those of ordinary skill that the flanges can also be formed in a folded configuration similar to that described above. The body 272b includes corresponding lip features 88 that can be formed into the body by the process described above.重叠 When the sheet is bent along the bending line, the overlapping structure 2 77b is formed at the corner (shown in Fig. 17F). The sheet further covers the panel 312'. The panel is secured to the inside of the curved configuration by securing the lip 314' to the corresponding lip 316' that becomes the inner wall (shown in Figure 17F). A number of panels can be placed within the curved configuration to modify the layout and structure of the three-dimensional construction to be formed. Referring to Figures 1 71-1 7J, a three-dimensional configuration can be formed by bending the sheet product along a curved line. Additional structural features can then be added and the Q construction can be completed. In various embodiments, the mounting trailer is attached to the bent configuration to support the construction and provide a mounting surface for the door. Foot, label, insulation, wire, and other structural features and combinations are further added during the final processing. The average person can understand that the above process can be modified according to different applications. It is also possible to change the order of the steps. The manner in which the structural features are formed within the wafer can be varied, and/or performed in a different process. The size of the three-dimensional product to be formed can also be easily modified by changing the width of the entire roll of stock material and/or cutting the cut, cutting the strip, and punching the shape, position, and timing of the punch -34-200940203. Other modifications and variations are considered to be within the scope of the invention. Turning now to Figure 18, the illustrated three-dimensional configuration, generally exemplified by 30, shows some aspects of the present invention. The exemplified construction 30 can be modified for integration with the exemplary cookware described above, or as a separate appliance. In some aspects, construction 30 is similar to construction 230 described above. Φ In the illustrated embodiment, the three-dimensional configuration 30 is a housing configuration having a hinged cover, such as an appliance (such as a stove, dishwasher, washing machine, or dryer), a container (such as a safe, a toolbox) , or cabinets, or enclosures. The illustrated furnaces are typically formed from two-dimensional sheet members, some of which may be pre-assembled components, and others may be combined on site. 21A-21P illustrate an exemplary method of forming a three-dimensional configuration of various aspects of the present invention. With the above-described process of forming the structure 203 illustrated in Fig. 17, the method of forming the structuring 30 allows the flat transport parts to be combined remotely. The process described below also requires a large interconnection of parts and more manual labor in the process. However, it is generally understood that the process of the present invention can be modified depending on the application. The selective table 32, which will be described in more detail below, provides a stable platform for bending and forming various sub-parts of a three-dimensional configuration. In the illustrated embodiment, the table has extensions in three directions to provide a working surface for forming the sides of the furnace. Since the front of the furnace includes the doors and gauges of the furnace, etc., these components can be pre-combined elsewhere as a sub-assembly&apos; and fixed to the housing construction during the combination period -35-200940203. However, these components can also be combined using methods similar to those described herein. In fact, by constructing a sheet material prepared in accordance with the principles described herein and using, for example, the methods disclosed in the '934 and '216 applications above, it is possible to form a majority, if not all, of the components and bodies of the furnace. Referring to Figure 18', an exemplary three-dimensional configuration of the inner furnace chamber includes a generally box-like inner core configuration 33 formed of - or more two-dimensional sheet material 35. In the illustrated embodiment, the internal configuration 33 is formed from five sheets&apos; but it will be understood by those of ordinary skill that the internal construction may be formed from one, two, three' or more sheets of material. As will be described below, each of the sheet material may be a rigid member that does not have a curved line or may have one or more curved lines 37 to facilitate bending into a three-dimensional configuration to form an internal configuration. In another embodiment, the internal configuration can be an integrated preformed three-dimensional configuration. The internal configuration is disposed within the housing 39, which is also formed by bending one or more two-dimensional sheet material 40 into a three-dimensional configuration. It is also possible to construct the sheet material 4 to be bent along the plurality of bending lines 42 similarly to the above sheet. The plurality of curved lines further define a side or panel 44 of the housing, and a profile. In the illustrated embodiment, each side 44 forms a generally flat surface of the housing construction (see, for example, Figure 24), although it will be appreciated by those of ordinary skill that other shapes and configurations can be defined. For example, the sheet can be stamped to have ribs, and/or other structural features, and/or decorative details that can strengthen, favorably combine, and/or improve structural integrity or aesthetics. The internal configuration and the curved line of the housing include a plurality of locating formations 46' to facilitate the designation of a position where one of the outer sides is curved along one or more of the other curved sides - 36 - * 200940203. In an exemplary embodiment, at least one positioning formation 46a is formed on the first panel portion 47a to nest within another positioning formation 46a on the second panel portion 49b such that the panel portion is along the shell The outside of the body lies flat. In one embodiment, the positioning formation is formed on the housing, and one or both of the internal construction and/or any number of other components to be transported in a flat shape and then bent into a three-dimensional configuration; The two-dimensional state, φ, is then bent into a three-dimensional configuration. In the illustrated embodiment, a plurality of bending inducing configurations are formed in the thickness direction of the sheets 35 and 40. In the illustrated embodiment, the sheet material forming the housing includes a peripheral flange portion 53 along a respective bend line 42 that extends along the panel portion 54 of the sheet material. A bend line extends around the perimeter of the panel portion to form a peripheral flange portion. As best shown in Figure 21G, the peripheral flange portion includes an outer tab or flap along the panel portion 54. In the illustrated embodiment, the peripheral flange portion extends from a curved line 界定 defining the periphery of the exterior of the panel. During the bending process, the peripheral flanges are bent along individual bending lines before the panel portion is bent. The surrounding flanges are used for several purposes. As shown in Figures 21M through 210, the peripheral edge provides a portion of the sheet to be coupled to the housing 39 when bent about the inner configuration 33. Each of the peripheral flanges also overlaps each other along the variable edge 51 of the housing such that the edges and corners of the housing have a multi-layered sheet. For example, when the peripheral flange and the individual panel portion 54 are bent over the other panel side 54b of the housing, the "surrounding flange will overlap a portion of the adjacent panel 54b" and create a two-piece thick structure (see, for example, Figure 23A). Thus -37-200940203 each surrounding flange portion and individual panels cover the curved or circumferential flange of the other panel to form a double layer thickness architecture. The edges and corners of the construction typically carry an important load on the construction, so the above structure allows for additional material thickness in the main load bearing portion of the construction. In this manner, the illustrated housing construction has a skeletal architecture that increases material thickness and strength along the edges and corners, but does not increase the overall thickness of the overall construction. In the illustrated embodiment shown in Fig. 23A, the sheet material includes a first peripheral flange portion 53a and a second peripheral flange portion 53b. The first peripheral flange portion 53a overlaps the first panel portion 54a of the sheet material along the first bending line. The second peripheral flange portion 53b overlaps the second panel portion 54b of the sheet material along the second bending line. Thus the surrounding flange and panel forming structure 56 has an additional thickness along the edge of the housing for additional support. In the illustrated embodiment, the structure has a two-piece thickness along the perimeter of the three-dimensional configuration, thus defining a load-bearing architecture. Referring again to Figures 21H through 21L, the internal configuration can include one or more support flanges 58 that extend outwardly from the periphery of the internal configuration and that are constructed to engage the housing. The internal configuration is placed in a covered configuration within the housing, as shown in Figures 21L-21P, and Figures 23A-24. Each support flange extends toward an individual bend line 42 of the housing. In the case where the internal construction 33 includes a curved curve, the support flange extends from the internal configuration to the structure 56 of the housing 39. Turning to Figures 21-23, the internal construction includes an internal skeletal configuration 60 formed along the perimeter of the internal construction. The inner skeletal configuration is formed by a combination of an inner edge 61, an inner structural flange 58, and an internal structure. Internal -38- . 200940203 Constructs the edges and flanges along the inner structure around the corners. In the illustrated internal configuration, the flanges extend from each other from the respective inner structural edge to the curved line of the housing to extend the overlapping structure, the overlapping flanges are secured to each other to the inner configuration or, therefore, the flange supports the inner skeletal structure 60 to prevent movement by The flange supports the internal structure in a "matchbox" type. Further, when the internal structure is disposed on the inner side of the housing, the housing and the housing can reinforce each other. Referring to Figure 23A, the first end extends into a crease or hook 63 formed by individual bend lines of the housing. The opposite corners of each flange extend to the corners or edges of the internal construction so as to be supported by the internal configuration via the flange. At least two of the flanges in one embodiment are radially opposed from opposite sides of the inner configuration. In the illustrated embodiment, at least 〇 straight. In this manner, the housing and internal configuration are locked by the movement of side 44 and bending line 42 to apply a compressive force to individual flanges ί 33 . Referring again to Figure 13, the curved side of the housing can be mounted in a similar manner. The interior configuration can have any number and configuration of flanges that can be varied, as described above, by modifying the housing and internal construction flanges to a three-dimensional configuration to be formed, depending on the application. For example, the internal structure may bend the ball or curved portion on the inside of the line or edge. Or the vertices are combined in a stack. Each flange. Depending on the panel of the special housing. . In this way, 'and vice versa' the inner frame of each flange 58 of the hook portion 63 is bent from the end of the bending line to the inside of the housing, the plurality of flanges are extended such that the one flange is substantial, such that the shell Body; 8 and internal structure of the body like a matchbox, understandable structure. Depending on the number of edges. Having the housing, in this case, -39-200940203 can be constructed such that the flange is circumferential about the surface of the inner construction and substantially conforms to the inner structural surface and extends to the housing bending line. In another example, the flange may not extend exactly from the inner construction edge to the housing bend line. Instead, a flange can be constructed to be secured to a portion of each individual configuration that is adjacent to or away from the edge. The above structure may be desirable when another component is to be placed at the corner or edge, or some other design constraints require moving the flange mounting point. Referring again to Figures 21-23, in one embodiment, each support flange includes a securing formation 65 on its outer edge 67 to secure the flange to the housing, thereby securing the internal configuration to the housing, and Maintain the meshing between the flange and the individual bend lines (see, for example, Figure 27). The fixed configuration of each of the inner structural support flanges incorporates the individual positioning formations of the housing 39 to support the inner structure 33 within the housing. In an embodiment, the fixed configuration has a tab or slot structure. The fixed configuration 65 includes tabs 68 along the individual bend lines 42 or hooks 63 of the housing and individual slots or apertures 70. The fixed structure 65 is preferably integrally formed from individual sheet materials, as is the case with the illustrated embodiment. The tabs can be inserted into the holes during or after the bending, thereby engaging the individual support flanges of the internal construction to a portion of the housing. As shown, 'a plurality of fixed configurations' are provided to engage each of the lateral corners of the inner structure with the individual corners of the housing to spatially secure the inner structure to the housing. In this embodiment, each of the support flanges can be secured to the housing without a separate securing configuration. Instead, the flange 58 locks into the hook 63 of the bend line when the tab 68 engages the corresponding aperture 70 during the combined three-dimensional configuration. In another. In the embodiment of the 200940203, the flange may not extend into the hook of the individual bend line at all and/or the flange may include an intermediate configuration to engage the housing. As noted above, the flange can be secured to one of the housing or internal configuration, or the flange can be formed in one of the housing or internal configuration. In another example, the flange can be freely disposed between the inner construction and the housing. For example, one of the shell or internal construction may use an alignment configuration to align the flanges during the curved housing. Once the housing is formed, the flange can be held in the hook of the individual bend @ line. Other fixed configurations may also be used, including but not limited to those described in the '440 application above. Such fixed configurations include, but are not limited to, tie mounts, fasteners, bolts, and the like. The construction, size, and structure can be varied depending on the application. In one embodiment, at least one of the flanges is configured to extend at an acute angle from the interior to the housing, the acute angle being at an angle to the plane defined by the interior side of the internal structure 33. In one embodiment, at least one of the flanges extends approximately 45 degrees from the plane. Other G structures include, but are not limited to, the size and shape of the design flange 58 for special applications. For example, the sizing of the flange can be used to provide movement to prevent bending of the housing, or the flange can be constructed to provide elastic force or "give" to the entire three-dimensional configuration. Because each flange effectively guides or limits the movement of individual bend lines, the flanges can be constructed in a variety of ways to &amp; control the overall rigidity and motion of the three dimensional configuration. Furthermore, more than one flange (especially the flanges on opposite corners of the internal construction) can be constructed to affect and control the physical characteristics of the three-dimensional structure. When the housing 39 is wrapped around the inner structure 33, the internal configuration imparts strength and rigidity to the housing -41 and 200940203, and vice versa. In an embodiment, the housing is a loosely formed configuration having an independent minimum strength. The internal construction and flange impart strength to the housing construction and the overall three-dimensional construction. In particular, the flanges secure and support individual bend lines of the housing. In one embodiment, the housing and internal construction are independent of each other and do not have significant strength. It will be understood by those of ordinary skill that the internal configuration 33, the flanges 58, and the housing 39 can be configured in a variety of ways to increase the stiffness and strength of the resulting three dimensional construction. In the illustrated embodiment, the internal construction and the flange form a cross-over support within the housing whereby the internal structure of the furnace box is formed to complement the furnace shell. Similar to the housing, the internal configuration 33 can be formed from at least one inner sheet material 35b (including the inner bend line 74b). In one embodiment, the support flange 58 and at least one inner panel are integrally formed and the inner bend line defines a boundary between at least the support flange and the inner side 72. As shown in Fig. 22, during the bent internal configuration, the flange is formed by overlapping the panels on the sheet material. The inner bending line defines a boundary between the inner side surface and the support flange. In one embodiment, the housing sheet material 40 and the at least one support flange are integrally formed. In one embodiment, one of the housing and the inner construction sheet material includes a lip 75. Where the lip extends from the housing, the curved line of sheet material defines the boundary between the side panel 54 and the lip. The lip extends toward the inner configuration in the direction of the substantially parallel flange portion. In one embodiment, the internal configuration is formed from at least two sheets of material, one of which includes a curved line. The lip extends from the bend line such that it helps the end of the flange to be at the edge or bend line of the internal construction. A lip can be used to secure the lip to -42- *200940203 with one less support flange 58. In another embodiment, the fasteners that do not require separation can also secure the lip to the individual flanges. The lip is constructed to provide additional support for the three-dimensional construction 30 and the reinforcement flange 58 is secured between the inner construction and the housing. The lip is also used as a support point for the flange. Housings can be constructed for a variety of applications. The casing in the illustrated embodiment is constructed as a furnace casing. Therefore, the housing is constructed for the module control panel 77 to be mounted to the housing. The housing further includes at least one aperture 79 that provides a guide path for the electrical wire and a mounting point for the furnace door. The housing can be constructed in other ways, as is known to those skilled in the art, regardless of the formation of the appliance or any other three-dimensional construction. The above-mentioned application No. M40 describes a similar structure for a power supply line and the like. As described below, a specific application structure can be fabricated at any stage from the preparation of the sheet material to the formation of a three-dimensional process between the final processing after bending the sheet material. Materials suitable for use in the housing and/or internal construction include, but are not limited to, metals, plastics, and other materials. In an embodiment, the internal construction and/or the housing are formed from a relatively incompressible and rigid sheet material. Therefore, conventional paper and ester board products are not considered to be incompressible. In the illustrated embodiment, the housing and internal construction are stainless steel. Similar materials can also be used for the flange. Various materials can also be used depending on whether the application requires strength, rigidity, chemical inertness, corrosion resistance, and the like. An exemplary method of making the three-dimensional construction of various aspects of the present invention is now described. Referring to Figures 21A-21P, a combined system of the present invention is shown. The components of the furnace can be fabricated in a conventional first station or forming zone containing a metal forming apparatus. In particular, the sheet material 40 can be prepared to have the one-piece configuration of the above-mentioned -43-200940203 position and the fixed configuration. As described above, the positioning configuration can be formed similarly to the process described in the '450 patent above and with reference to Figure 17 above. In addition, other basic parts (whether plastic, natural materials, or others) can be prepared in the forming area. In the illustrated embodiment, the furnace construction body is primarily comprised of steel sheets that are prepared for bending. Therefore, the forming station includes processing equipment for cutting a plurality of sheets and preparing a complex bending inducing structure. For example, a bending induction structure can be prepared using a computer numerical control (CNC) processing machine. The outer dimensions of the sheet material are also important and are also prepared in a similar apparatus. The side 72 of the internal construction can also be prepared at this station or at other locations. It is generally understood that these steps can be prepared on one or more stations. The formation station can also be remote from the area where the rest of the manufacturing process is performed. In particular, the sheet material forming the casing (whether a single sheet or a plurality of sheets constructed to be joined together) can be formed at one position and conveyed in a flat shape to another position. In one embodiment, the positioning configuration of each of the sheets is constructed to accommodate a positioning configuration of the adjacent sheet material. Thus, when the sheet materials are stacked one on top of the other, the positioning structure within the body is nested within the positioning structure of the adjacent sheet material. This reduces the package size when the sheet material is transported in a flat shape for bending at a distance. Referring to Figures 21A through 21P, the housing may be formed from a single sheet of material or formed from a plurality of sheet materials and then joined together. In the illustrated embodiment, the housing is formed from a two-dimensional sheet material 40 formed from three separate forming sections 40'. The first section 40a is placed on the table 32, and the peripheral flange 53 is bent upward by the edge -44 - *200940203. The first section includes a portion that becomes the first side panel 534a and the bottom portion 81 of the housing. Second, the second section 40b is placed on a table adjacent the area of the first panel. The second section includes a portion that becomes the second side panel 54b and the housing top portion 82. The surrounding flange of the second panel is then bent into position. Finally, the third section 40c is placed on the workbench. The third segment overlaps 一 a portion of the first segment. In the illustrated embodiment, the peripheral flanges of the first and third sections overlap each other and are bent to form a mounting point for the flange 58 (see, for example, Figure 21G). In particular, the two sections can be joined together to form the edge flange portion 84. Then bend the other surrounding flanges on the third section upwards. These steps are repeated until all of the sheet material is placed on the table and the surrounding flanges are bent. After the sheet material of each segment is positioned and prepared, the segments are joined together by a fastener construction. Various configurations are available. In the illustrated embodiment, the fastener construction is similar to that described above, including but not limited to tab-and-slot fasteners, bolts, tongue-and-groove fixation Pieces and so on. The fixed structure also includes welding, adhesion, and the like. In the illustrated embodiment, the rivets are used to further secure the panels together into a single piece of material (see, for example, Figure 21G).

The internal constructions of Figs. 21H to 21M' are incorporated on the casing. The first side portion 72a of the inner structure is fixed to the sheet of material 40. The side portion includes a flange 58' at the distal edge that is secured to the lip of the housing (see Figures 21H-45-200940203). As shown in Figure 211, the side portions are then bent upwardly to a position perpendicular to the sheet material, and particularly perpendicular to the bottom. Next, the other side portions 72b, 72c are fixed to the sheet material and the first side portion. The three sides form an internally configured cavity which, in the illustrated embodiment, will become a furnace box. The top side 72d is then placed on top of the side portion and secured to the top. In the illustrated embodiment, the top side includes three flanges 58' that overlap the flanges 58" on each of the side portions 72a, 72b, 72c. Thus the flanges have a double thickness. As shown, the projections The periphery of the inner structure extends along the corner to the edge of the corner. The increased thickness of the flange and the internal structure of the corners form the inner skeleton structure 60.

In the illustrated embodiment, a plurality of panel portions or sides 72 are joined together to form an internal configuration. In the illustrated embodiment, the 'internal construction includes an overlapping configuration 91 (e.g., a winged flange) that follows the perimeter or forms an edge of a type of skeleton configuration (see, for example, Figures 23A-46-*200940203) because of overlapping materials This skeleton construction has increased rigidity and strength. In another embodiment, a conventional method (e.g., fusion sheet material) forms an internal configuration. In one embodiment, the internal configuration is formed from a two-dimensional sheet material similar to the housing. In another embodiment, the detachable fasteners (see, for example, Figure 23B) secure the overlapping formations 91 together, or the overlapping formations can be a single sheet above itself (see, for example, Figures 23C, 23D). In addition, the angle of the overlapping 构造 configuration can be changed (see, for example, Figure 23C). Additionally, tabs 73 may be provided at the ends of the flanges 58 that are adapted to extend into and engage the bores 73' of the body. This configuration allows the full length position of the internal construction to be fixed relative to the housing (see Figure 23B). The flange 58 can also be formed prior to transporting the prepared parts and sheets. A flange can be formed at the forming station or at the location. The flange can also be integrally formed with the internal construction or housing. After the internal construction is placed over the housing panel, the flange is secured to the internal configuration. Each flange is secured such that it extends from the internal configuration 33 to an individual curved line of the housing. In the illustrated embodiment, each of the flanges extends from the inner flange of the inner configuration into a crease formed by the curved line of the housing. As described above, a plurality of edge flange portions 84 may also be provided on the housing. To strengthen the flange construction. The edge flange portion is a portion of the material that extends in substantially the same direction as each of the flanges 58 and is located at the opposite end of each flange from the lip portion 75. The edge flange portion performs a function similar to the lip. Similar to the lip and the inner structural flange, the edge flange portion can be integrally formed with the housing or separately formed and then secured. In one embodiment, the edge projections -47 - 200940203 edges may be integrally formed with the sheet material 40 having additional curved lines and panels to form an accordion-like edge flange portion. Bend the sides of the housing along the bend line. Next, the first side of the edge flange portion is bent, and then the second side of the same edge flange portion is bent back and overlaps the first side surface. In this manner, the edge flange portion has the thickness of the two sheets and imparts additional strength to the housing and the attachment flange ends. If the edge flange portion is defined by a curved line having a displacement, the bending control of the bending line defining the first edge flange portion can be configured to be nested in a curved line defining the flange portion of the second edge. Within the displacement. The flange 58 and the lip 75 can also be formed in the same manner so that the entire hearth and the casing can be formed from a plurality of sheets and materials. Referring to Figures 21M through 21P, a second station 93 is provided to facilitate bending the sheet material into a three-dimensional configuration. In an embodiment, the bending station includes a table 32. After the sheet material is prepared in the formation region, the sheet body intended to form the shell is placed on the table, and the three-dimensional structure is formed by bending the sheet. The second section 4〇b is bent around the first bending line and then around the second bending line until the second section covers the back of the internal construction (see, for example, Figure 2 1N). Once bent about the inner configuration, the peripheral flange wraps around the edges of the inner structure such that a portion of the peripheral flange and the side of the inner structure overlap. In the illustrated embodiment, the two bend lines engage the edges of the internal construction when the sheet material is bent. Specifically, the curved line chews the end of the flange 58. Second, the other sections of the sheet material are bent around the inner structure in a similar manner until the shell is formed. In this way, the housing is formed around the internal configuration to form a rigid three-dimensional configuration. 48 _ *200940203 Again, in the illustrated embodiment, the housing and internal configuration are constructed such that each flange extends from the bend of the housing to the abutting edge of the inner construction. Extending the flange 'from each edge of the internal configuration such that when viewed from a direction orthogonal to the side of the configuration, the flanges on the opposite edges extend in the same direction, and in particular through the diagonal of the internal configuration Boundary to boundary (see, for example, Figure 6 6). As clearly shown in Figure 28, a table 32 can be constructed to facilitate bending the sheet material into a three-dimensional configuration and combining the finished products. In the illustrated embodiment, the table includes hinged flaps corresponding to the faces of the construction. The curved line of the hinge corresponds to a curved line within the housing such that when the flap is rotated, the sheet material is accurately bent along the curved curve. The flaps further provide additional leverage to the user during bending and minimize contact between the workpiece and the table. This protects the user's hands from being scratched or cut by the workpiece and also reduces the amount of dirt and dirt on the workpiece by the user's hands. The workbench can also be constructed as described in the patent application No. 2006/0053857 to the entire disclosure of the entire disclosure of the entire disclosure of the entire disclosure of bending. Furthermore, the workbench 33 can be constructed for flat transport and further combined into a more three-dimensional configuration. In the illustrated embodiment, the table is formed from a flat piece of material 'the pieces of flat material are joined together at a combined location. The individual pieces of material may be secured by conventional fasteners, or the individual pieces of material may be pre-joined by a hinge or the like to allow for bending into a solid three-dimensional shape as shown. Structures other than the above may also be used depending on the application. Place the sheet material and internal construction on the bench. The internal configuration formed at the first -49-200940203 workstation is placed on the sheet material such that the fixed configuration 65 engages or positions the configuration 46. The sheet material is then bent into a three-dimensional shell along a curved line. The internal configuration remains positioned within the housing such that the housing encases around the internal construction and then couples the housing to retain it in the bent position. The housing may be coupled by a fastener or the like which is integrally formed or separately formed from the sheet. In the bent position, the fixed configuration supports the internal configuration relative to the outer housing construction. The constructable flange acts as a support for both the internal construction and the housing such that the two structural sides support each other. For example, in the illustrated embodiment, the flange is constructed as a cross beam and the interior is constructed on the inside of the housing. The flange also supports and maintains the position of the internal structural edges. Other components may be attached to the construction during the bending process. The furnace heating element can be attached, for example, before or after bending the sheet material 40. The furnace door can also be attached to the station before the bending process is completed. In one embodiment, the edges of the housing form a structure that exceeds the thickness of the two sheets. In this embodiment, the "first peripheral flange portion and a portion of the second panel portion of the sheet overlap" and the second peripheral flange portion overlaps a portion of the first panel portion. As shown in Figure 21M, the first bend defining the first peripheral flange immediately abuts and is parallel to the second bend defining the second peripheral flange. This results in a two-piece thickness architecture that overlaps the first and second peripheral flange portions by surrounding the three-dimensional configuration. Further, the flange portion forms an architecture of three or more sheet thicknesses when bent over the individual panel portions in this manner. This can be combined with three, four and more surrounding flanges and a portion of the sheet material. The 200940203 configuration moves from the bending station 93 to the assembly and final processing station 95. In this final processing station, the construction transitions from the support bone structure to the final and finished product, in this case the finished product is the furnace. In the illustrated embodiment, the various sub-combinations are fixed to the furnace body. These sub-combinations include wires, control panels, and heating sub-combinations. If the furnace includes a selective roof, then the pre-assembled roof assembly can be secured to the top of the furnace at this station. Likewise, if the door has not been secured to the configuration 'the door can be secured at the bending station. As is familiar to the art, as the artisan knows, several other functions can be performed at the final processing station or bending station, including (but not limited to) installing wires and tubing, additional decorative panels, additional adjustments, and trim panels. These functions can also be performed at an earlier point in the manufacturing process. Referring to Figure 21K, it should be noted that many components can be installed inside the cavity in this battle. Referring to Figure 21L, a number of components can be mounted to the exterior of the cavity at a combination of this stage.

Referring to Figure 4P', one can appreciate that many of the components and/or sub-assemblies can be attached to the assembly by pre-attachment. For example, a control panel sub-assembly can be attached to the assembly. A three-dimensional configuration can also be formed from the sheet material of the present invention such that many typical final processing processes are not required. For example, in a forming station, objects can be stamped directly into the sheet material to replace the brand name. It is also possible to apply paint to the sheet material after the forming, instead of replacing the end of the remanufacturing process with the finished paint of the three-51 - 200940203 dimension. In many cases, this flexibility allows for an opportunity to reduce manufacturing costs and increase efficiency. In another exemplary embodiment of the present invention, the internal configuration 33a is similar to the internal configuration 33 described above, but as shown in Figures 29A to 29D, the internal configuration 33a includes two sheet materials instead of five sheet materials. form. Like reference numerals are used to describe like components of internal construction 33 and internal construction 33a. In this embodiment, the four inner sides 72a are integrally formed from a single piece of material and interconnected by flanges 58a that are configured to be bent back to the inner side 72a (see, for example, Figure 29a). It will be appreciated by those of ordinary skill that the geometrical layout of interconnect structure 93 is particularly well suited for nesting and transporting in a flat shape. This embodiment is particularly suitable for use as a flat glaze, i.e., a layer of enamel 97 to interconnect structure 98 may be applied in a substantially two-dimensional configuration and before the construction is bent. In this embodiment, the layer of enamel can be applied to the unitary construction (including along the trough 99 and over the trough 99) by dipping, coating, or other suitable means. In addition, it is also possible to bake enamel in a flat shape or to harden the enamel. When bent, the only enamel that is directly exposed to the bend will be directly in the groove, and if the enamel layer fails (eg, cracked, broken, etc.), the failed area will overlap the flange 58a and the furnace The hole is isolated, so you can't see it. The overlapping portions can also be modified as described above and illustrated in Figure 13. In various embodiments, the positioning configuration is formed in consideration of aesthetic factors. In some embodiments, the locating formations within the sheet material forming the housing all form a side of the re-bending line such that when the sheet is bent, the locating formation forms -52 - • 200940203 into a smooth edge. Such constructions and modifications are similar to those described in the aforementioned '216 application and the '426 patent. After the final processing station, the combined system may also include one or more inspection locations, and other quality control/quality assurance (QA/QC) processes. In the illustrated embodiment, the combined system includes a test station (not shown) after the last processing station. As you can see from the discussion above, you can perform several processes at each station or offline. For example, painting, building sub-assemblies, installing wires and functional equipment, and the like can be performed at any number of stations. In another embodiment, many of the components can be fully prepared at another location and attached to the construction somewhere in the combined line. As will be appreciated by those skilled in the art, the combined system can be constructed in many other ways. The three-dimensional construction and method of the present invention allows for greater flexibility within the combined system. In particular, because the use of tools, skilled labor, and heavy equipment is greatly reduced, the manufacturing system can be constructed in a manner that is impossible in the conventional method. For example, the bending station and the forming station can be separated and distinguished from each other. In addition, the above-mentioned combined system of most (if not all) can be moved out of the factory. In fact, in the illustrated embodiment, table 32 and workstation 93 are portable. Furthermore, the precise combination procedure performed to prepare the housing and internal construction depends on the design and manufacturing constraints of the three-dimensional construction. In the illustrated embodiment, the item to be manufactured is a furnace having a square housing and a square internal configuration. Other manufactured articles may have different design shapes and configurations that require changes in the order and type of execution processes to maintain the spirit of the above-described manufacturing method. -53- 200940203 The above construction and method have several advantages over conventional constructions. The above construction and method allow for precise bending into an accurate three-dimensional configuration. Further, the construction and method of the present invention have a good strength with respect to the conventional three-dimensional structure (including those formed by two-dimensional sheet material). For example, the internal construction and the housing can be constructed to complement each other and provide added protection against the resulting construction to prevent buckling, collapse, and shaking. Furthermore, additional support can be placed in selected areas of the construction, such as along the edges and corners. The construction of the present invention will further provide additional material thickness along the edges of the housing to form a rigid stock price configuration. In this way, the three-dimensional structure can have excellent strength without using unnecessary materials. The construction architecture also increases resistance to dents and failures. Conventional combination processes are more complex and more material in comparison to the constructions and methods of the present invention. For example, conventional devices are typically formed by welding thick and heavy gauge sheets. The sheet must be thick enough to ensure that the sheet conforms to the desired position in the fixture prior to welding. The sheets and processes of the present invention allow for a simple combination of at least half of the individual members. Each of these pieces can be easily modified and adjusted. By using the above principles to form positioning information within the wafer, the clamping problem can be reduced or eliminated. Furthermore, the components can be more easily mixed and matched to other components. The entire range of different appliances can be manufactured, for example, by simply changing the width of the roll of material, cutting different shapes, timing of the strip stamping process, and/or attaching fewer or more panels at different locations. As described above, when the flat sheet is subjected to application processing, finishing, and other functions as compared with the complicated three-dimensional configuration, it has better results and lower cost. Among other benefits, the method of the present invention also reduces the cost of the main-54-.200940203 (eg, tool cost and fewer unique parts), increases flexibility and modularization, and reduces product planning and operation ( Roll-out) time. In the same way, the energy of the used portion can be reduced because the process is greatly simplified and the use of bulky tools and machines is reduced. Furthermore, it has been found that the use of relatively thin sheet materials reduces heat flow from the heating compartment. In contrast, conventional appliances typically require bulky storage materials for structural strength. Thus, the heated compartment of the present invention not only uses less © material, but also has better performance characteristics. In cases where it is desired to increase heat transfer, holes or other configurations may be added to increase the flow of heat. In other words, the thickness of the material to be formed is not required to be specified by the strength requirements of the construction. Instead, the construction can be made according to the customer's specifications for improved performance with less waste. Moreover, other aspects of the construction of the present invention are more susceptible to modification for various performance parameters than conventional configurations. For example, to find the above-described overlapping configuration, heat loss from the heating compartment can be reduced. The amount and structure of the overlap can be adjusted to reduce the heat seal in the compartment. For the convenience of explanation and accurate definition of the attached request item, "up" or "upper", "down" or "lower", "inside" or "outside" The words "outside" are used to describe the configurations of the present invention with reference to the positions of the configurations shown in the drawings. The modification of each figure in many aspects is similar to the previous modification, and the same reference numerals followed by subscripts "a", "b", "c", and "d" represent corresponding parts. 55- 200940203 The description of the specific illustrative embodiments of the above text invention is presented for purposes of illustration and description.
