New description: [New technical field] The creation of this case is a furnace body forming structure, especially a kind of heat preservation effect, and the outer barrel can be set with a thin plate to reduce the cost and still have appropriate strength. When the inner tub is broken, the replaced furnace body forming structure can be taken out. 1 Prior Art] According to the general furnace body (especially the water heater heated by electric energy), the outer barrel is built into an inner barrel, and the outer barrel and the inner barrel have a space between them and an insulating layer of heat insulating material is arranged. When the inner tank is filled with water, it can be insulated by the insulation layer. The traditional furnace body has two molding methods (please refer to the first and second figures at the same time), which is built into the outer barrel 1 - an inner tub 11 and a gap between the outer tub 10 and the inner tub 嗣, the liquid foaming agent can be injected into the gap, the 俟 foaming agent expands to fill the gap to form the heat insulating layer 12; In this way, since the heat insulating layer 12 has a better combination with the outer tub 10 and the inner ►bar 11 , the heat insulating effect is better and the outer tub 10 can be thinned due to the support of the heat insulating layer 12 . Sheet (reducing cost = still maintaining proper strength; however, because the inner barrel u is in contact with the insulation layer 121, male, and then, if the inner barrel (four) is damaged and needs to be replaced, the inner barrel η can not be taken. The furnace body is the second of the financial formula (please same as 3!: three, four maps) The outer tub 20, the inner tub 21 and the pre-heated insulation layer 22 are sequentially arranged, and the outer tub 2 〇, the heat preservation (four) and the inner tub Μ == are formed into a furnace body; this manner is because the insulation layer 22 and the inner tub 21 are If the inner barrel 21 is damaged and needs to be replaced, the inner barrel M304641 21 can be replaced by the insulation layer 2 2 逵隹 φ / , but the outer barrel 20, the inner barrel 21 and the temperature layer 2 2 are not replaced. Close n | industry, α = 1 # Λ, pick-up, 峒 its thermal insulation effect is poor, and the outer barrel 20 lacks the thermal insulation layer 2 2, the old-fashioned, and the ^ ^ mountain support must be set with thicker plates (cost increase) to maintain proper green; $: I 0 field ^ intensity. Because of the advantages of the above two traditional furnaces, there are advantages to be improved - there is a lack of improvement, in view of this, for further improvement The actual harvesting energy of the furnace body, the (4) person is the result of many (four) tests, but the creation of this creation. [New content] The purpose of the creation of this case is to provide a thin insulation plate with a good insulation effect and a thin barrel. In order to reduce the cost and still have the appropriate strength, the replacement of the furnace body forming structure can be taken out when the inner tub is broken. The technical means and the characteristics of the creation of the case for the purpose of creation are as follows: Please refer to the preferred embodiment shown in the figure as follows: , q Please also refer to the fifth figure, I macro name λ mouth The creation of the case is mainly in the outer barrel 30. The inner mold is placed in an inner mold 4, so that the outer barrel 3〇 and the inner mold 4 m and the Π AL ^ have a space therebetween, and the outer surface of the inner chess 4 设Shaped 皙f _; mussels (such as · release agent, release film, etc.), 2 the outer barrel 30 and the inner mold 4 〇 in the distance between the injection of liquid foaming agent, 俟 foaming Weng with expansion Filling the gap to form the heat preservation (4) (as shown in the sixth figure), since the outer surface of the inner mold 40 is provided with a detachment, ^ ^ 丨 negative, the inner mold 40 can be self-protected, and the dish is pulled away '( As shown in the seventh figure, here, the inner barrel 32 (the inner diameter of the anastomosis insulation layer 31) conforming to the inner mold 40:: is placed inside the insulation layer, and the body is formed into a furnace body (such as the eighth figure). Shown). M3 04641 [Embodiment] With the structure of the above-mentioned furnace body, since the inner mold 4 is placed in the outer tub 30, the foaming agent is injected to form the heat insulating layer 31, and the inner mold 40 and the inner tub 32 are replaced, thereby completing the furnace. Therefore, the thermal insulation layer 31 and the outer tub 3 have a better combination, so that the heat preservation effect is better, and the outer tub 3 is supported by the thermal insulation layer, and the crucible can be set with a thinner plate. Maintaining proper strength, in particular, the separation between the guava layer 31 and the inner tub 32 is broken. Therefore, the inner tub 32 is broken and needs to be replaced. The inner tub 32 can be removed from the heat insulating layer 31 to improve the practical performance of the furnace body. By. Further, the form of the above-mentioned furnace in the present invention is an embodiment in which a through-drum is used, and it can also be an embodiment having a bottom. In addition to this: it can also be implemented in the form of an oval, rectangular or other polygonal furnace. As can be seen from the above description of the preferred embodiments shown in the drawings, the creation of the case utilizes the cooperation of the outer tub 30 and the inner mold 40, and then the work is carried out; Sex 2; is based on 'this case compared with the well-known, it has significant progress and practicality, and its technical means and its construction are indeed developed for this case. Sakamoto (4) Chengcheng has met the new patent The essentials: the law makes an application, and the patent is granted as a prayer. The disclosure of this document is a preferred embodiment. The changes in the creation of the case should still be covered by the patent application scope of this creation.
