Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cooking oven equipped with an external conveyance mechanism.

[Conventional technology]

A cooking oven is equipped with a mechanism for moving the heated material within the furnace in order to uniformly heat the heated material within the furnace. Conventionally, the conveyance mechanism for this purpose consists of rotatably arranging bars on which the material to be heated is placed at predetermined intervals between opposing chains, and attaching sprockets to the ends of the bars.
By meshing these sprockets easily, a device is adopted in which the material to be heated is conveyed while being rotated by conveyance by the chain and rotation by the sprocket.

[Problem that the invention attempts to solve]

However, since such a conveyance mechanism is disposed within the furnace, various problems remain unsolved. For example, since the conveyance mechanism is designed to be placed inside the furnace, the size of the chain is limited by the size of the heating chamber and becomes small, resulting in insufficient structural strength against the load. Moreover, since the chain itself is heated by the heat inside the furnace, it is likely to deteriorate. As a result, the material to be heated is conveyed in an unsteady manner, and the life of the rotating mechanism itself is shortened.

In addition, since the bar itself moves in the conveying direction as the chain circulates, it is difficult to install a heat source at the bottom of the bar, and heating can only be done from the top, so the material to be heated is unevenly distributed over a short conveying distance. Another problem was that it was difficult to bake to a high quality.

Furthermore, since the bar and chain were attached as one piece, maintenance and repairs were time-consuming.

Therefore, the present invention has been devised in view of the problems that exist in ovens in which a rotating mechanism is placed inside the furnace. The purpose is to move smoothly inside the oven.

[Means for solving problems]

In order to achieve the purpose, the oven of the present invention has a driving side wheel and a driven side wheel respectively disposed in the front and back direction on both outside sides of a heating chamber having side plates on both sides. A conveyor belt is stretched between each side, U-shaped notches are formed at required intervals along the longitudinal direction of the both side plates, and the belts are respectively stretched between the opposing U-shaped notches of the both side plates. The present invention is characterized in that it is equipped with a conveying mechanism in which a rod-shaped or cylindrical conveying member for conveying the material to be heated is rotatably coupled to the upper end of which the lower circumferential surface of the end portion is slidably contacted.

〔Example〕

Next, features of the present invention will be specifically explained with reference to embodiments shown in the drawings.

FIG. 1 shows the overall structure of the oven in this embodiment, FIG. 2 is a side view thereof, and FIG. 3 shows the main parts of the conveyance mechanism.

This oven is roughly composed of a heating section 1, a transport mechanism 2, and a control unit 3. The heating section 1 has an upper heating surface 4 and a lower heating surface 5, and a heating chamber 6 between these heating surfaces 4 and 5.
is formed. A hood 7 is attached above the upper heating surface 4, and hot air in the heating chamber 6 is exhausted through the hood 7. The transport mechanism 2 includes a driving wheel 10 connected to a motor 8 via a power transmission mechanism 9, and a driven wheel 11 facing the driving wheel 10.
It also includes a conveyor belt 12 (see FIG. 3) stretched between the wheels 10 and 11. In addition, so that the belt 12 does not become slack,
A tension roller 16 is provided midway on the return side of the belt 12.

As shown in FIG. 3, side plates 14, 14 (only one is shown in the figure) are provided on both outer sides of the heating chamber 6, and a rod-shaped or cylindrical conveying member 13 is mounted on the same side plate. U-shaped notches 14A for rotatably supporting the heated material are formed at predetermined intervals with gaps sufficient to prevent the heated material from falling. Conveying member 13
By simply attaching both ends of the conveyor member 13 to these notches 14A, the conveyor member 13 is rotatably fitted to the side plate 14. At this time, the lower portions of the circumferential surfaces of both ends of the conveying member 13 come into sliding contact with the upper surface of the conveying belt 12 under their own weight.

The control unit 3 includes a control panel 15 attached to the entire surface of the oven, as shown in FIG.
Each operating part such as a power supply voltage regulator and main switch is arranged.

Next, the operation of the oven of this embodiment will be explained to clarify the operation of the present invention.

The end of the conveying member 13 rests on the conveying belt 12 through a U-shaped notch 14A provided in the side plate 14, and since the conveying member 13 cannot be moved by the notch 14A, the belt 12 The conveyance member 13 rotates within the cutout portion 14A due to friction with the cutout portion 14A. Therefore, the material to be heated is transported on the many arranged transport members 13 in a direction opposite to the running direction of the transport belt 12.

The material to be heated is placed in the heating chamber 6 in the direction of the arrow in FIG.
and moves on the circumferential surface of the conveying member 13. Inside the heating chamber 6, heating is performed by an upper heating surface 4 and a lower heating surface 5. At this time, one or both of the heating surfaces 4 and 5 is used depending on the purpose of heating.

At this time, the conveying member 13 is moved to the side plate 1 of the heating chamber 6.
A conveyor belt 12 for transmitting driving force passes through the
Since the power transmission mechanism is in sliding contact with the heating chamber 6, the power transmission mechanism is not exposed to the high temperature inside the heating chamber 6. In addition, since only the conveying member 13 of the conveying mechanism is disposed inside the heating chamber 6, the internal volume of the heating chamber 6 can be increased, and there are no parts inside the heating chamber 6 that block heat radiation. Thermal efficiency can be improved since there is no such thing.

[Effect of idea]

As explained above, all the transport mechanisms in the oven of the present invention are located outside the heating chamber, so there is no deterioration due to heat. Further, since the material to be heated is transported only by a rod-shaped or cylindrical transport member without using a chain unlike the conventional transport mechanism, there is no noise during transport. The areas near both ends of the conveying member only fit loosely in the U-shaped cutouts provided in the side plates, so there is no need for complex mechanisms such as bearings that require maintenance and replacement to rotatably support the conveying member. This makes it possible to assemble and replace the conveying member itself extremely easily. Furthermore, since the number of parts in the conveyance mechanism placed inside the heating chamber is small, the internal volume of the heating chamber can be used effectively, and there are fewer obstacles to heat radiation, which improves thermal efficiency. I can do it.
