Abstract

<P>PROBLEM TO BE SOLVED: To provide a structure for a door of a deck oven in the deck oven usable for baking, humid baking or the like of a bread, a Western-style cake or the like. <P>SOLUTION: The structure for the door of the deck oven has a door body enabling an opening part connected to the interior of the deck oven to be opened and closed. The periphery part of the door body has an inside stepped face and an outside stepped face formed so as to correspond to an inside stepped part and an outside stepped part imparted to a door-receiving frame defining the opening part, respectively, and packings are provided between the inside stepped face of the door-receiving frame body and the inside stepped face of the door body, and between the outside tiered face of the door-receiving frame body and the outside tiered face of the door body. As a result, the escape of the heat from the door is reduced and the formation of unevenness or the like of baking is prevented by doubling the packings. The mechanical strength of the door is increased and the deformation of the door is prevented by forming the structure of the door into a doubly stepped shape to reduce the inconvenience caused thereby. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a deck oven used for baking or humidifying and baking bread, western confectionery, and the like, and particularly relates to a door structure in a deck oven.
[0002]
[Prior art]
In this type of deck oven, a door for opening and closing an opening on the front side of the furnace is provided in order to enable a material to be fired to be taken in and out of the furnace of the oven. Then, in order to prevent the heat inside the furnace from being released when performing firing or humidification firing, packing is preferably applied between the door and a door receiving frame body on the side of the oven body that defines an opening of the furnace. Normal. Conventionally, such a packing is simply applied in a single layer between the periphery of the door and the corresponding periphery of the door receiving body.

[Problems to be solved by the invention]
In the structure of the door of such a conventional deck oven, the packing provided between the door and the door receiving frame body is only a single layer. However, the following problems tend to occur. In other words, if a single packing ages or a gap is created between the periphery of the door and the door receiving frame, this will immediately release the heat inside the furnace from the periphery of the door. This has led to inconveniences such as uneven firing during firing.
[0005]
In addition, the peripheral part of the door of the conventional deck oven has a one-stage structure and is easily deformed mechanically. Such deformation of the door also causes a gap to be formed between the door and the door receiving frame, causing heat to escape from the inside of the furnace, thus leading to uneven grilling.
[0006]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a deck oven door structure that can solve the above-mentioned problems of the prior art.
[0007]
[Means for Solving the Problems]
According to the present invention, in the structure of the door of the deck oven, a door body capable of opening and closing an opening of the deck oven into the furnace is provided, and a peripheral portion of the door body has a door defining the opening. An inner step surface and an outer step surface which can be respectively opposed to the inner step surface and the outer step surface given to the receiving frame body are formed, and the inner step surface of the door receiving frame and the inner step surface of the door main body are formed. The structure of the door of the deck oven is provided, wherein packing is provided between the outer step surface of the door receiving frame and the outer step surface of the door body.
[0008]
According to one embodiment of the present invention, the packing is attached to an inner step surface and an outer step surface of the door receiving frame.
[0009]
According to another embodiment of the present invention, the packing is attached to an inner step surface and an outer step surface of the door body.
.
[0010]
According to still another embodiment of the present invention, the packing includes one of an inner step surface and an outer step surface of the door receiving frame, and an inner step surface and an outer step surface of the door body. Attached to the other side of the house.
[0011]
