       [0001]    1. Field of the Invention 
         [0002]    The present invention in general relates to a product of home appliance, in particular, to a roasting oven for cooking food by a thermal flow manner and to a heightened structure of its oven wall. 
         [0003]    2. Description of Prior Art 
         [0004]    Accordingly, a prior baking oven, mainly for baking the Western-style pastry such as bread, cake and biscuit, is a kind of baking oven that cooks food by means of high temperature. However, following daily emphasis by people on eating and drinking, manners of cooking food also increase, due to the requirement of dainty by people. Besides baking the aforementioned foods, current baking oven also needs to roast meat or food such as chicken occupying large volume and space. 
         [0005]    However, the space of common roasting oven used in home is quite limited in terms of space for accommodating food so, when baking or roasting the meat or food such as chicken occupying large volume or space, an oven wall of ring shape has to be additionally arranged onto the original roasting oven. After heightening the oven wall of the original roasting oven, although the problem of the limitation of the interior space can be solved, the prior oven wall of ring type for increasing the interior space of the roasting oven is a rigid structure that is integrally made and unable to be dismantled or folded, so many problems such as the occupation of large space when not used are incurred to the user. In addition, for the manufacturer, when the products of roasting oven are packaged or transported, the derived shortcomings of the occupation of large space are also incurred, due to the increasing space in the interior of the roasting oven. 
         [0006]    Therefore, how to improve and solve the aforementioned problems is an issue intended to be addressed by the inventor. 
         [0007]    Accordingly, after a substantially devoted study, in cooperation with the application of relatively academic principles, the inventor has finally proposed the present invention that is designed reasonably to possess the capability to improve the drawbacks of the prior arts significantly. 
       SUMMARY OF THE INVENTION 
       [0008]    The invention is mainly to provide a roasting oven structure and a heightened structural improvement of its oven wall, in which an oven wall of ring type is adapted for increasing the interior space of the roasting oven, constituting an assembling manner capable of dismantlement. In other words, the oven wall can be disassembled to thereby reduce the space occupation when not used, so it is convenient for the accommodation, the package and the transportation of the product, effectively solving the aforementioned problems and shortcomings. 
         [0009]    Secondly, the invention is to provide a roasting oven structure, which includes an oven body, an oven lid and a heightened oven wall shown as a ring shape and placed on the oven body, while the oven lid covers the heightened oven wall. According to the invention, the heightened oven wall is assembled by plural sections of wall parts capable of being dismantled. The heightened oven wall capable of being disassembled is assembled by connecting each section of wall part together, thereby, the aforementioned objectives being achieved effectively. 
         [0010]    Thirdly, the invention is to provide a heightened structural improvement of the oven wall of a roasting oven, which is assembled between an oven body and an oven lid, and which is an enclosure of oven wall shown as a ring shape and arranged by connecting plural sections of wall parts capable of being dismantled. Since the heightened oven wall is assembled by each section of wall part and is capable of being dismantled, the aforementioned objective is thereby achieved. 
         [0011]    Compared to the prior arts, since the heightened oven wall of the invention is assembled with a capability of being dismantled, for the user, it is easy to accommodate the product when not used; on the other hand, for the manufacturer, it is also convenient for packaging and transporting the product to further reduce the unnecessary storing space and transporting cost.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0021]    In cooperation with attached drawings, the technical contents and detailed description of the present invention are described thereinafter according to a number of preferable embodiments, not used to limit its executing scope. Any equivalent variation and modification made according to appended claims is all covered by the claims claimed by the present invention. 
         [0022]    Please refer to  FIG. 1  and  FIG. 2 , which respectively are a perspective explosive illustration and a perspective assembled illustration of the invention. The invention is mainly to provide a roasting oven structure and a heightened structural improvement of its oven wall, in which the roasting oven structure includes an oven body  1 , an oven lid  2  and a heightened oven wall  3 . By assembling the heightened oven wall  3  between the oven body  1  and the oven lid  2 , the accommodating space loadable by the oven body  1  increases and the roasting oven can bake and roast with larger and more food ingredients. 
         [0023]    The oven body  1 , made of a material with high temperature resistance, is constituted by a ring wall  10  with continuous enclosure and a bottom wall  11  closely connected to the bottom part of the ring wall  10 , such that an accommodating space  12  is formed in the oven body  1  for loading the food or ingredients to be cooked. 
         [0024]    The oven lid  2  can be optionally arranged by covering onto the oven body  1  or the heightened oven wall  3 . In the meantime, a heating unit  20  capable of roasting or baking function can be placed onto the oven lid  2  to generate a thermal flow for undergoing a baking or roasting task to the food ingredients intended to be cooked in the oven body  1 . When the oven lid  2  corresponds to the oven body  1 , on the upper edge of the ring wall  10  of the oven body  1 , a ring flange  13  turned to the outside is formed. The form enclosed by the inner edge face  130  of the ring flange  13  is conformable to the form of the outer edge of the oven lid  2  and is tightly matched therewith in a way, such that the closed space formed in the oven body  1  can prevent hot gas from releasing out. In addition, an oven seat  14  can be further arranged under the oven body  1  to support the oven body  1  with protecting functions of stable installation and thermal insulation. 
         [0025]    When the food ingredients for the oven body  1  are too large or too many to be cooked, the heightened oven wall  3  can increase the space and the capacity loadable by the oven body  1 . Please refer to  FIG. 3  and  FIG. 4  together. When the heightened oven wall  3  is placed on the oven body  1 , the oven lid  2  then covers the heightened oven wall  3  correspondingly. The heightened oven wall  3  is at least constituted by plural sections of wall parts  30 ,  31 , which can be assembled with a capability of being dismantled, such that an oven wall structure shown as a ring enclosure is thereby formed. In the embodiments proposed by the invention, the wall parts include two first wall parts  30  and two second wall parts  31 , in which the cross-sectional profile of the first wall part  30  is shown as a “U” letter. Both the first wall parts  30  are arranged by corresponding to each other and are connected by both the second wall parts  31  to constitute a form conformable to the form enclosed by the inner edge face  130  of the ring flange  13  of the oven body  1 . In the meantime, tightly connecting bottom edges  300 ,  310  turned to the outside are formed at the lower edges of the first and second wall parts  30 ,  31  and can be tightly abutted onto the inner edge face  130  along the inner peripheral of the ring flange  13 . Thereby, the heightened oven wall  3  can be placed onto the oven body  1  tightly to increase the space and the capacity loadable by the oven body  1 . 
         [0026]    As shown in  FIG. 5  and  FIG. 6 , with respect to the assembly between each pair of the first and second wall parts  30 ,  31  of the heightened oven wall  3 , two vertical plates  301 ,  311  extended inwardly are arranged at two adjacent sides of the wall parts  30 ,  31  to be connected together. Rolled-and-fitted plates  302 ,  312  extended from the ends of the vertical plates  301 ,  311  are shown as cured reel shapes. Any pair of the rolled-and-fitted plates  302 ,  312  at two adjacent sides of the wall parts  30 ,  31  to be connected together is fitted by enveloping the inside with the outside, such that each pair of oven walls  30 ,  31  can be assembled with a capability of being dismantled. In the embodiments proposed by the invention, the radian formed by the rolled-and-fitted plate  302  of the first wall part  30  is larger than that of the rolled-and-fitted plate  312  of the second wall part  31 , while the outer arc of the rolled-and-fitted plate  312  of the second wall part  31  is in cooperation with the inner arc of the rolled-and-fitted plate  302  of the first wall part  30 , such that the rolled-and-fitted plate  312  of the second wall part  31  can be placed into the rolled-and-fitted plate  302  of the first wall part  301  from top to bottom, as shown in  FIG. 7  and  FIG. 8 . By the fitting cooperation between the rolled-and-fitted plates  302 ,  312  of the first and second wall parts  30 ,  31 , the heightened oven wall  3  can be assembled with a capability of being dismantled. Furthermore, a stop plate  305  can be further arranged at lower end of the rolled-and-fitted plate  302  of the first wall part  30  such that, after the rolled-and-fitted plate  312  of the second wall part  31  is fitted therein and abutted against its end, it can prevent the rolled-and-fitted plate  312  of the second wall part  31  from sliding downwardly continuously. 
         [0027]    In addition, in order to make the oven lid  2  closely covered on the heightened oven wall  3 , flanges  304 ,  314  turned to outside are also formed on the upper edges of the first and second wall parts  30 ,  31 . When the first and second wall parts  30 ,  31  are assembled to form the heightened oven wall  3 , the flanges  304 ,  314  of the first and second wall parts  30 ,  31  can just constitute a ring shape, such that the form enclosed by the inner edge faces  303 ,  313  of the flanges  304 ,  314  of the first and second wall parts  30 ,  31  is conformable to the outer edge form of the oven lid  20  and is tightly matched therewith to make the oven lid  2  able to be tightly covered on the heightened oven wall  3 . 
         [0028]    Summarizing aforementioned description, the invention is an indispensably novel structure for a compressor indeed, which may positively reach the expected usage objective for solving the drawbacks of the prior arts, and which extremely possesses the innovation and progressiveness to completely fulfill the applying merits of new type patent, according to which the invention is thereby applied.
